Question

Zach saved x dollars over the last year. Mina saved \large \frac{3}{5} more than Zach. Which equation can be used to find how much money Mina saved last year?

a. y = 3.5x
b. y = 0.6x
c. y = 1.4x
d. y = 1.6x

Answer 1

Mina saved 3/5 more than Zach, which translates to the equation y = x + 0.6x or y = 1.6x. Therefore, the correct answer is y = 1.6x.

Step-by-step explanation:

Zach saved x dollars over the last year, and Mina saved rac{3}{5} more than Zach did. To find out how much money Mina saved, we add three-fifths of the amount Zach saved to Zach's total savings. This can be expressed as the equation:

Mina's savings (y) = Zach's savings (x) + rac{3}{5} × Zach's savings (x)

Combining the terms for Zach's savings, we get:

y = x + 0.6x = 1.6x

Therefore, the correct equation to represent how much money Mina saved is y = 1.6x, which is choice (d).
