Question

Please help!!!!!

Billy and Susie were saving up to buy the new Xbox. Billy got $50 for his birthday and saved $20 each week. Susie already had $25 and saved $40 each week. Write a system of equations to describe this situation.

Answer 1

50+ 20x= y

25+ 40x= y

Explanation:

For Billy and Susie, the starting values are $50 and $25. You simply add that to the money saved per week ($20 and $40).

x= number of weeks

Answer 2

I’m not quite sure but what about...

Billy —> $50 + $20 * x
Susie—>$25 +$40 * x

I’m not sure how to continue though. My apologies if this is incorrect.
