Keisha the trainer has two solo workout plans that she offers her clients: Plan A and Plan B. Each client does either one or the

gregori [183]

Answer:

Plan A last 0.75 hours or 45 minutes.

Plan B last 1.5 hours or 90 minutes.

Step-by-step explanation:

Let $a$ be the number of hours that the plan A last, an $b$ the number of hours of plan B. Then for the Wednesday you have:

$2a+3b=6$

And for the Thursday is:

$6a+5b=12$

Multiply the equation of Wednesday by -3:

$-6a-9b=-18$

Using the method of addition using this last equation and the equation of Thursday

$-6a-9b=-18\\6a+5b=12\\--------\\-4b=-6\\b=\frac{-6}{-4}\\b=1.5 hours$

Replacing the value of $b$ in one of the equations

$6a+5b=12\\6a+5(1.5)=12\\6a+7.5=12\\6a=12-7.5\\a=\frac{4.5}{6} \\a=0.75hours$
