Answer:
108 ft²
Step-by-step explanation:
The product of length and width is ...
(12 ft)(9 ft) = 12·9 ft·ft = 108 ft²
PART A
apples = a
bananas = b
a + b = 20
$0.50a + $0.75b = $11.50
PART B
a + b = 20
a +b -b = 20 - b
a = 20 -b
$0.50(20-b) + $0.75b = $11.50
10 - 0.50b + 0.75b = $11.50
10 + 0.25b = 11.50
10 -10 + 0.25b = 11.50 -10
0.25b = 1.5
0.25b/0.25 = 1.5/0.25
b = 6
a = 20 -b
a = 20 -6
a = 14
PART C
Missy bought 14 apples and 6 banans.
Check
$0.50(14) + $0.75(6) = $11.50
$7 + $4.50 = $11.50
$11.50 = $11.50
Answer:
108ft^2
