Ответ:
3 weeks and $40
Step-by-step explanation:
Let the number or weeks taken for them to have same amount be represented by x.
The information given in the question can be presented as an equation as:
Stephanie = 25 + 5x
Jose = 16 + 8x
We then equate them together
25 + 5x = 16 + 8x
25 - 16 = 8x - 5x
3x = 9
x = 9/3 = 3
The number of weeks is 3
The amount of money that they'll have will be:
= 25 + 5x
= 25 + 5(3)
= 25 + 15 = $40
