Marlon has a gift card for $200. He spent half of it on Monday and one-fourth of the remainder on Tuesday. How much was left on his gift card?

Since Marlon spent half of the gift card, then half of it which is $200/2 = $

<<200/2=100>>100 remained on Monday. Then on Tuesday, he spent $100/4 = $<<100/4=25>>25. Therefore, he has $100 - $25 = $<<100-25=75>>75 left in his gift card. #### 75 James has 20 years of experience. 8 years ago John had twice as much experience as James. Mike started when John had 16 years of experience. What is their combined experience? 8 years ago James had 20-8=<<20-8=12>>12 years So 8 years ago John had 12*2=24 years experience That means John has 24+8=<<24+8=32>>32 years experience So Mike has 32-16=<<32-16=16>>16 years of experience So together they have 20+32+16=<<20+32+16=68>>68 years experience #### 68 Susan loves chairs. In her house there are red chairs, yellow chairs, and blue chairs. There are 5 red chairs. There are 4 times as many yellow chairs as red chairs, and there are 2 fewer blue chairs than yellow chairs. How many chairs are there in Susan's house? The number of yellow chairs is 5 chairs × 4 = <<5*4=20>>20 chairs. The number of blue chairs is 20 chairs − 2 chairs = <<20-2=18>>18 chairs. There are 5 chairs + 20 chairs + 18 chairs = <<5+20+18=43>>43 chairs in Susan's house. #### 43 Before work, Hayden spends 5 minutes ironing his button-up shirt and 3 minutes ironing his pants. He does this 5 days a week. How many minutes does he iron over 4 weeks? He spends 5 minutes ironing his shirt and 3 minutes ironing his pants so that's 5+3 = <<5+3=8>>8 minutes He does this every day for 5 days so that's 5*8 = <<5*8=40>>40 minutes After 4 weeks, Hayden has spent 4*40 = <<4*40=160>>160 minutes ironing his clothes #### 160 Henry believes in the famous phrase, "An apple a day, keeps the doctor away." If a box contains 14 apples, how many weeks can Henry and his brother spend eating 3 boxes of apples if they each eat 1 apple a day? There are a total of 14 apples/box x 3 boxes = <<14*3=42>>42 apples in the 3 boxes. So, Henry and his brother each have 42 apples / 2 people = <<42/2=21>>21 apples/person to consume. Since there are 7 days in a week, thus, both of them can consume the 3 boxes of apples in 21 / 7 = 3 weeks. #### 3 Katy participated in a summer reading program at her local library. She read 8 books in June, twice as many in July and three fewer in August than she did in July. How many books did Katy read during the summer? Katy read twice as many books in July as she did in June, so she read 2 * 8 = <<2*8=16>>16 books in July. She read three fewer books in August than she did in July, so she read 16 - 3 = <<16-3=13>>13 books in August. So, including June, she read 8 + 16 + 13 = <<8+16+13=37>>37 books total #### 37 A gecko lays 30 eggs per year. 20 percent of them are infertile, and a third of the remaining eggs will not hatch due to calcification issues. How many eggs actually hatch? Infertile:30(.20)=6 30-6=<<30-6=24>>24 eggs remain Calcification Issues:24(1/3)=8 24-8=<<24-8=16>>16 eggs that will hatch #### 16 Chantal knits sweaters to sell. Each sweater takes 4 balls of yarn. Each ball of yarn costs $6. How much money will Chantal gain in all 28 sweaters if she sells each sweater for $35? The 28 sweaters need 28 x 4 = <<28*4=112>>112 balls of yarn. So, Chantal will spend 112 x $6 = $<<112*6=672>>672 in all for the balls of yarn. Her total earnings for selling 28 sweaters is $35 x 28 = $<<35*28=980>>980. Therefore, Chantal will gain $980 - $672 = $<<980-672=308>>308. #### 308 A party store ordered 5 boxes of balloons. Each box contains 8 bags of balloons, and there are 12 balloons in each bag. How many balloons are there? The five boxes have a total of 5 x 8 = <<5*8=40>>40 bags of balloons. So, there are 40 x 12 = <<40*12=480>>480 balloons. #### 480 Jenn is saving up money to buy a bike. She has 5 jars full of quarters. Each jar can hold 160 quarters. If the bike costs 180 dollars, how much money will she have left over after buying it? Jenn has 5 * 160 = <<5*160=800>>800 quarters. The quarters are worth 800 * 0.25 = <<800*0.25=200>>200 dollars. After buying the bike she will have 200 - 180 = <<200-180=20>>20 dollars left. #### 20
