Answer:
The store charges $9.77 to ship a hammock that weighs 10.54 pounds.
Explanation:
4.50 (shipping cost)
0.50 (per 1 pound)
w = weight in pounds
w=10.54
4.50+0.50w= total cost
sub in 10.54 for w
remember order of operations (PEMDAS)
4.50 + 0.50 (10.54) = 4.50 + 5.27 = 9.77
The store charges $9.77 to ship a hammock that weighs 10.54 pounds.
