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

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
