Answer:
C. 74 sqft
Step-by-step explanation:
The bottom has a surface area of 4ft * 5ft = 20sqft
Theres two 3ft x 5ft sides and two 3ft x 4ft ones.
2 * 3ft * 5ft + 2 * 3ft * 4ft = 2 * 15sqft + 2 * 12sqft = 30sqft + 24sqft = 54sqft
Total surface of the outside is thus
20sqft + 54sqft = 74sqft

Expanding all the binomials, we have
Sum like terms:
Simplify terms appearing on both sides:
Move all terms involving k to the left and all numbers to the right:
Divide both sides by -20:
Answer:
$814.13
Step-by-step explanation:
Recall that the simple interest formula is a=p(1+rt).
a= final amount (Unknown)
p=starting amount ($780)
r= interest rate (5.25= 0.0525%)
t=time in years (10 months =5/6 years)
Plug numbers into formula:
a=780(1+5.25*5/6)
Solve parenthesis first according to PEMDAS:
a=780(1.04375)
Multiply:
814.125
Round to nearest hundredth (cent):
$814.13
