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 gasoline 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

B. y=2.49x+5.57

Step-by-step explanation:

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

answer: t=3

step-by-step explanation:

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
