Washer = $616, Dryer = $308

Max and Sasha exercise a total of 20 hours each week. Max exercises 15 hours less than 4 times the

navik [9.2K]

Answer:

Max exercises 13 hours a week, and Sasha 7.

Step-by-step explanation:

To find the number of hours each of them exercises during the week, we solve the system of equations.

In the second equation:

$x = 4y - 15$

Replacing in the first equation:

$x + y = 20$

$4y - 15 + y = 20$

$5y = 35$

$y = \frac{35}{5}$

$y = 7$

So Sasha exercises 7 hours per week.

Max:

$x + y = 20$

$x + 7 = 20$

$x = 13$

Max exercises 13 hours a week.
