Angela is a bike messenger in New York. She needs to deliver 8 times as many packages as meals. If she needs to deliver 27 meals and packages combined, how many meals does she deliver?

Let p be the number of packages Angela delivers and m be the number of meals. We know that p + m = 27 and p = 8m.

Substituting the second equation into the first equation, we get 8m + m = 27

Combining like terms, we get 9m = 27

Dividing both sides by 9, we get m = 3

#### 3

Keiko sent 111 text messages last week. This week she sent 50 less than double what she sent last week. How many text messages did Keiko send last week and this week combined?

Last week = 111 texts

This week = (2 * 111) - 50 =

<<(2*111)-50=172>>172 texts 111 + 172 = <<111+172=283>>283 texts Keiko sent 283 texts last week and this week combined. #### 283 A one-year subscription to a newspaper is offered with a 45% discount. How much does the discounted subscription cost if a subscription normally costs $80? We calculate first the discount: 80 * 45 / 100 = $<<80*45/100=36>>36 So, the discounted subscription amounts to 80 – 36 = $<<80-36=44>>44 #### 44 Tim's cat bit him. He decided to get himself and the cat checked out. His doctor's visits $300 and insurance covered 75%. His cat's visit cost $120 and his pet insurance covered $60. How much did he pay? The insurance covers 300*.75=$<<300*.75=225>>225 So he had to pay 300-225=$<<300-225=75>>75 The cats visit cost 120-60=$<<120-60=60>>60 So in total he paid 75+60=$<<75+60=135>>135 #### 135 Ariella has $200 more in her son's saving account than Daniella has in her son's savings account. Ariella's account earns her simple interest at the rate of 10% per annum. If Daniella has $400, how much money will Arialla have after two years? If Ariella has $200 more in her son's saving account than Daniella has, then she has $400 + $200 = $600 If she earns an interest of 10% in the first year, her savings account increases by 10/100 * $600 = $<<10/100*600=60>>60 In the second year, she earns the same amount of interest, which $60 + $60 = $<<60+60=120>>120 The total amount of money in Ariella's account after two years is $600 + $120 = $<<600+120=720>>720 #### 720 Colby harvested his mango trees, the total mangoes he harvested is 60 kilograms. He sold 20 kilograms to the market and sold the remaining half to his community. If each kilogram contains 8 mangoes, how many mangoes does he still have? He has 60-20= <<60-20=40>>40 kilograms of mangoes left after selling them to the market. Colby sold 1/2 x 40 = <<1/2*40=20>>20 kilograms of mangoes to the community. Therefore, Colby still has 20x8= <<20*8=160>>160 pieces of mangoes. #### 160 George bought some food for his trip: a bottle of juice, a sandwich, and a bottle of milk. The sandwich was for $4, and the juice was two times more expensive. The bottle of milk cost was 75% of the total cost of the sandwich and juice. How much did George pay for his food? The juice was two times more expensive than the sandwich, so it was 4 * 2 = $<<2*4=8>>8. The juice and the sandwich in total were a cost of 4 + 8 = $<<4+8=12>>12. So the cost of one bottle of milk was 75/100 * 12 = $<<75/100*12=9>>9. In total for all the food, George paid 12 + 9 = $<<12+9=21>>21. #### 21 A young girl pours 23 blue beads and 16 yellow beads into a bowl. She divides the total into 3 equal parts, removes some beads from each part, and doubles the rest to have 6 beads in each part now. How many beads were removed from each part? There are 23+16=<<23+16=39>>39 beads in the bowl Dividing them into 3 equal parts give 39/3=<<39/3=13>>13 beads each Before doubling the number of beads, she had 6/2=<<6/2=3>>3 beads left in each part. Therefore she had removed 13-3=<<13-3=10>>10 beads from each part. #### 10 Jerome is taking a 150-mile bicycle trip. He wants to ride 12 miles for 12 days. How long will he ride on the 13th day to finish his goal? Jerome rides a total of 12 x 12 = <<12*12=144>>144 miles in 12 days. So, he will ride 150 - 144 = <<150-144=6>>6 miles on the 13th day to finish his goal. #### 6 At Mario's barbershop haircuts are 50% more expensive during the weekends. If Mario paid $18 for his last haircut on Monday, how much he would have paid the day before? Mario's $18 cut on Monday would have been 50% more expensive on Sunday or $18*50% = $<<18*50*.01=9>>9 more expensive That means he would have paid $9 more on Sunday than what he paid ($18) on Monday or $9+$18 = $<<9+18=27>>27 #### 27
