Answer:
y = 49
Step-by-step explanation:
Given y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 21 when x = 6 , then
21 = 6k ( divide both sides by 6 )
3.5 = k
y = 3.5x ← equation of variation
When x = 14 , then
y = 3.5 × 14 = 49
Answer:
A. $8.80
Step-by-step explanation:
$9.28 x 2.5 = $23.20
$12.80 x 2.5 = $32.00
$32.00 - $23.30 = $8.80
B. 8 lbs. caramel and 2 lbs. chocolate
Step-by-step explanation:
$9.28 x 8 = $74.24
$12.80 x 2 = $25.60
$74.24 + $25.60 = $99.84
