Answer :
Given:
total cost : 28.70
cost per pint of fruit : 2.85
Formula:
5v + 7f = 28.70
5v + 7(2.85) = 28.70
5v + 19.95 = 28.70
5v = 28.70 - 19.95
5v = 8.75
5v/5 = 8.75/5
v = 1.75 cost per pint of veggies.
to check:
v = 1.75 ; f = 2.85 ; total cost = 28.70
5v + 7f = 28.70
5(1.75) + 7(2.85) = 28.70
8.75 + 19.95 = 28.70
28.70 = 28.70
total cost : 28.70
cost per pint of fruit : 2.85
Formula:
5v + 7f = 28.70
5v + 7(2.85) = 28.70
5v + 19.95 = 28.70
5v = 28.70 - 19.95
5v = 8.75
5v/5 = 8.75/5
v = 1.75 cost per pint of veggies.
to check:
v = 1.75 ; f = 2.85 ; total cost = 28.70
5v + 7f = 28.70
5(1.75) + 7(2.85) = 28.70
8.75 + 19.95 = 28.70
28.70 = 28.70
