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 $2.59 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?

C = 2.99+ 2.58 +2.59x

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given.

The total cost for her (C) is equal to the price of the drink (2.99) ; plus the product of the price of each bag of chips (1.29) and the number of bags of chips that she bought(2); plus the product of amount of gallons of gasoline purchased (x) and the price of each gallon (2.59)

Mathematically speaking:

C =2.99 + (2)1.29 + 2.59 x

C = 2.99+ 2.58 +2.59x

step-by-step explanation:

starting with:    

5 + x - 12 = 2x - 7   

5 + x - 12 - x = 2x - 7 - x (subtract x from both sides)   

5 - 12 = x - 7 (combine and cancel x's from both sides)   

5 - 12 + 7 = x - 7 + 7 (add 7 to both sides)   

0 = x (add numbers together on both sides)       

so in order for the equation to be true, x must be 0.   

trying x = -0.5   

5 + x - 12 = 2x - 7 (original equation)   

5 + -0.5 - 12 = 2(-0.5) - 7 (plug in value of x)   

5 + -0.5 - 12 = -1 - 7 (did multiplication)   

-7.5 = -8 (did addition on both sides)       

since -7.5 is obviously not equal to -8, the value of -0.5 for x is wrong.   

trying x = 0   

5 + x - 12 = 2x - 7 (original equation)   

5 + 0 - 12 = 2(0) - 7 (plug in value of x)   

5 + 0 - 12 = 0 - 7 (did multiplication)   

-7 = -7 (did addition on both sides)       

since -7 equals -7, that demonstrates that the value of 0 for x is correct.   

trying x = 1   

5 + x - 12 = 2x - 7 (original equation)   

5 + 1 - 12 = 2(1) - 7 (plug in value of x)   

5 + 1 - 12 = 2 - 7 (did multiplication)   

-6 = -5 (did addition on both sides)       

since -6 is obviously not equal to -5, the value of 1 for x is wrong.
