Question

WORTH MANY POINTS PLEASE HELP..

Quincy paid $9.50 to join a photography club that allows him to print digital pictures for 0.20 each. So far he has paid $12.50 to the club. Write and solve an equation to work out how many pictures Quincy has paid for.​

Answer 1

9.50 + 0.20e = 12.50

Explanation:

you start with the 9.50, base price. Then with every photo you pay 0.20, since we don't know how many it is we put a variable. Then we know that those two combined is 12.50, so yeah.

Answer 2

Explanation:

Total Cost = base price + 0.20*x Where x is the number of prints printed.

12.50 = 9.50 + 0.20x Subtract 9.50 from both sides.

12.50 - 9.50 = 0.20x

3 = 0.20x Divide by 0.20

3/0.20 = x

x = 15

So he printed 15 prints.
