If a kitten weighed 100 grams at birth and gained 8 grams per day, which equation shows how many days it will take for the kitten to triple its weight?

• 300 = 100 – 8d

• 300 = 100 + 8d

• 100 = 300 + 8d

• 300 = 100d + 8

Ben had 7 less than triple as many customers as when he started selling newspapers. He now has 89 customers. How many customers did he have when he started?

• 7-3x and x= 2

• y = 7 - 3x and x = 5

• 89 = 3x - 7 and x = 32

• None of these are correct

Paulo has $145 in his savings account. He earns $36 a week mowing lawns. If Paulo saves all of his earnings, after how many weeks will he have $433 saved?

• 145 – 36w = 433

• 145w + 36 = 433

• 145w + 36 = 433
