Answer:
D. 9p + $11.50 = $94.75; p = $9.25
Step-by-step explanation:
To answer this problem, let p be the price of each scrub. The total bill (t) is the sum of the price of the potting soil (s) and of the 9 scrubs (n). This is depicted in the equation,
$11.50 + 9p = $94.75
The value of p from the equation is 9.25. Thus, each scrub costs $9.25. The answer is letter D.

Let
p---------> the price of each scrub
s----------> the price of the potting soil
T--------> total bill
we know that
in this problem

Answer:
480 cm²
Step-by-step explanation:
New side lengths:
80% of 30 cm = 0.8% × 30 cm = 24 cm
80% of 25 cm = 0.8 × 25 cm = 20 cm
area = length × width
area = 24 cm × 20 cm
area = 480 cm²
