The total cost, after using a 55cents-off coupon, is $3.30. If c represents the cost of the fruit in dollars per pound, wha
t equation could you use to find the value of c?
1 answer:
T= total cost= $3.30
c= cost of fruit per pound
x= # of pounds of fruit purchased
EQUATION
T= (c)(x) - $0.55 coupon
to find c, substitute $3.30 total for T
$3.30= cx - $0.55
add $0.55 to both sides
$3.85= cx
divide both sides by x
$3.85/x= c
Hope this helps! :)
