Answer:
A = $3.2
B = $0.2
C = $0.8
Step-by-step explanation:
First of all, convert the mixed fraction to improper fraction
2¾ pounds = 11/4 pounds
He bought 11 / 4 pounds for $8.80
11 / 4 pounds = $8.80
1 pounds = $x
X = [8.80 / (11/4)]
X = (8.8 * 4 ) / 11
X = $3.2
1 pounds cost $3.2
B.
1 pounds = 16 ounces
But 1 pounds cost $3.2
16 ounces = $3.2
1 ounces = $y
y = (1 * 3.2) / 16
y = $0.2
1 ounce costs $0.2
C.
The unit price of 1 ounce = $0.2
4 ounce = $z
Z = 4 * 0.2
Z = $0.8
The price of 4 ounces = $0.8
