Zilla spent 7% of her monthly earnings on rent, half of it on her other monthly expenses, and put the rest in her savings. If she spent $133 on her rent, how much does she deposit into her savings account in a month?

Since $133 is equal to 7% of her earnings, then 1% is equal to $133/7 = $

<<133/7=19>>19. The total monthly earning of Zilla is represented by 100%, so $19 x 100 = $<<19*100=1900>>1900 is her monthly earnings. So, $1900/2 = $<<1900/2=950>>950 is spent on her other monthly expenses. The total amount spent on the rent and other monthly expenses is $133 + $950 = $<<133+950=1083>>1083. Hence, she saves $1900 - $1083 = $<<1900-1083=817>>817 per month. #### 817 Jerry is refilling the duck pond in his backyard during a drought. The pond can hold 200 gallons of water. Jerry's hose can normally pump 6 gallons/minute, but due to drought restrictions, it can only pump 2/3rds as fast right now. How many minutes will it take Jerry to fill his pond? First find the current rate the hose pumps by multiplying its normal rate by 2/3: 6 gallons/minute * 2/3 = <<6*2/3=4>>4 gallons/minute Then divide the number of gallons in the pond by the number of gallons pumped each minute to find how many minutes filling the pond takes: 200 gallons / 4 gallons/minute = <<200/4=50>>50 minutes #### 50 Rohan owns a 20-square meter coconut farm. Each square meter has 2 coconut trees and each tree has 6 coconuts. If the coconuts can be harvested every 3 months and each coconut costs $0.50, how much will he earn after 6 months? Rohan has a total of 20 x 2 = <<20*2=40>>40 coconut trees. And he has a total of 40 x 6 = <<40*6=240>>240 coconuts. So, the total coconut he will have after 6 months is 240 x 2= <<240*2=480>>480. Therefore, the total amount he will earn is 480 x $0.50 = $<<480*0.5=240>>240. #### 240 Eddie can bake 3 pies a day. His sister can bake 6 pies while his mother can bake 8 pies a day. How many pies will they be able to bake in 7 days? Eddie bakes 3 x 7 = <<3*7=21>>21 pies for 7 days. His sister bakes 6 x 7 = <<6*7=42>>42 pies for 7 days. His mother can bake 8 x 7 = <<8*7=56>>56 pies for 7 days. Therefore, they are able to bake 21 + 42 + 56 = <<21+42+56=119>>119 pies in 7 days. #### 119 Jeff had 300 pencils and donated 30% of them. Vicki had twice as many pencils as Jeff and donated 3/4 of his pencils. How many pencils are there remaining altogether? Jeff donated 30/100*300 = <<30/100*300=90>>90 pencils. He remained with 300-90 = <<300-90=210>>210 pencils. Vicki had twice as many pencils as Jeff, meaning he had 2*300 = <<2*300=600>>600 pencils. When Vicki donated 3/4 of his pencils, he gave away 3/4*600= <<3/4*600=450>>450 pencils. Vicki remained with 600-450=<<600-450=150>>150 pencils. Together, Jeff and Vicki remained with 150+210 = <<150+210=360>>360 pencils. #### 360 Robie bought 3 bags of chocolates. She gave the 2 bags to her brothers and sisters then bought another 3 bags. How many bags of chocolates were left? She was left with 3 - 2= <<3-2=1>>1 bag of chocolate after she gave 2 bags to her brother and sisters. Therefore, the total number of bags of chocolates left after buying another 3 is 1 + 3= <<1+3=4>>4. #### 4 Lizzy's school choir has a mixture of 80 blonde and black-haired girls. Their teacher decides to add 10 more girls to the choir, who turns out to be blonde. If there were 30 blonde-haired girls in the choir initially, how many black-haired girls are present? The total number of girls in the choir is 80+ 10 = <<80+10=90>>90 girls. The total number of blondes in the choir after 10 more are added is 30+10 = <<30+10=40>>40 blonde-haired girls. From the total number, the number of black-haired girls is 90-40 = <<90-40=50>>50 black-haired-girls #### 50 Carmen is preparing dinner plates for a row of customers at the counter in a diner. She likes to put a couple of sprigs of parsley on each plate for decoration. However, she is very low on parsley and doesn't have enough to even put 1 sprig on every plate, so she needs to break several of the parsley sprigs in two to make 2 smaller ones to stretch them out. If she decorates 8 plates with one whole parsley sprig and 12 plates with 1/2 a sprig each, how many sprigs of parsley does she have left if she started with 25? Carmen decorates 8 plates with 1 whole sprig of parsley, 8 plates x 1 parsley sprig each = <<8*1=8>>8 parsley sprigs. She also decorates 12 plates with 1/2 a sprig each, 12 x 1/2 = <<12*1/2=6>>6 parsley sprigs. She started with 25 parsley sprigs and has used 8 + 6 = 14 parsley sprigs. After using 14 parsley sprigs, she has 25 - 14 = <<25-14=11>>11 sprigs left. #### 11 Wilson goes to a fast-food restaurant. He buys 2 hamburgers for $5 each and 3 bottles of cola for $2 each. Wilson uses his $4 discount coupon. How much money does he pay in total? 2 hamburgers cost 2*5=$<<2*5=10>>10 3 bottles of cola cost 3*2=$<<3*2=6>>6 The total price without discount is 10+6=$<<10+6=16>>16 With the discount coupon, it's 16-4=$<<16-4=12>>12 #### 12 Layla is training for a bicycle race. She rode her bicycle slowly to the high school, rode four miles around the running track at her faster, race pace, and then rode back home, slowly, on the same route. If her total mileage was 10 miles, how far is it, in miles, from Layla's house to the high school? Layla rode 10-4=<<10-4=6>>6 miles between home and the high school. Each leg of the round-trip journey was 6/2=<<6/2=3>>3 miles. #### 3
