Julie bought a drink for $2.99, two bags of chips for $1.29 each, and some gasoline at a convenience store. The price of gasolin
e was $2.49 per gallon. If x represents the number of gallons of gasoline she purchased, which of the following equations can be used to find how much Julie spent at the convenience store?
A.
y = 5.57x + 2.49
B.
y = 2.49x + 5.57
C.
y = 2.49x + 4.28
First, add the prices from the two items you know for sure the cost. You know gas is 2.49 a gallon but you do not know how much she bought. X will represent the amount of gallons, since it is unknown. hope is helps maybe someone can answer my math
