the same amount of money as Lena?
4 weeks
68 weeks
2 weeks
7.5 weeks

Answer 1

Amy will have the same amount of money as Lena in 4 weeks.

Step-by-step explanation:

To determine the number of weeks it will take for Amy to have the same amount of money as Lena, we can set up an equation. Let x represent the number of weeks. Amy's total saved money can be represented as 72 + 8x, and Lena's total saved money can be represented as 64 + 10x. We want to find the value of x when the two expressions are equal:

72 + 8x = 64 + 10x

Subtracting 8x from both sides, we get:

72 = 64 + 2x

Subtracting 64 from both sides, we get:

8 = 2x

Dividing both sides by 2, we get:

x = 4

Therefore, it will take 4 weeks for Amy to have the same amount of money as Lena.
