Four friends have collected $60 to buy dog food for an animal shelter. the food will cost $150. how much more does each friend need to collect if they will each collect the same amount

A. 15.00

B. 22.50

C. 37.50

D. 90.00

B.

150-60=90

This tells you how much the 4 friends still have to pay.

90/4=22.50

you divide the amount of money left that's not paid by the amount of friends. This gives you $22.50. This is the amount of money each friend needs to pay to reach their goal.

B because 150-60=90 and 90/4=22.5 and if you put 22.5 into money its 22.50
