Answer:

The maximum width of the pool must be 38 ft

Step-by-step explanation:

Let

y -----> the length of the swimming pool

x ----> the width of the swimming pool

The perimeter of the swimming pool is

P=2(x+y)

we have

y=22\ ft

substitute

P=2(x+22)

P=2x+44

Remember that

The perimeter of the pool must be no more than 120 feet

so

The inequality that represent this scenario is

2x+44 \leq 120

Solve for x

2x \leq 120-44

2x \leq 76

x \leq 38\ ft

therefore

The maximum width of the pool must be 38 ft

Rachel currently has $836 in a savings account that has earned 4. 5% annual compound interest for the past year. What was Rachel
prohojiy [21]
You would need to find 4.5% off of that $836 so 836 x 0.045= 37.62 now subtract that from the OG price so 836-37.62= 798.38 so one year ago her balance was $798.38
