Krystal went to the carry out to purchase some items. she purchased four bottles of pop, three candy bars, and two bags of chips. the pop was $1.25 per bottle in the candy bars were $.90 each. crystal could not find the price of the bag of chips. crystal had a coupon for $1.50 that she used. write an equation to determine crystals total bill (t) given the cost of one bag of chips.

Equation to determine crystals total bill (T) =(7.7+2x) - 1.50

Step-by-step explanation:

Given:

Number of bottles of pop purchased = 4

Number of candy bars purchased =  3

Number of chips bag  purchased = 2

Cost of per bottle of pop = $1.25

Cost of per candy bar = $.90

Cost of the coupon  = $1.50

To Find :

Equation to determine crystals total bill (T) given the cost of one bag of chips = ?

Solution:

Let the cost of one chips bag be x

Cost of  4 bottles of pop

=>

=>$ 5

Cost of 3 candy bars

=>

=>$ 2.7

Cost of 2 bags of chips

=>

=>$ 2x

Now the total cost of the bill is

T = 5 + 2.7+ 2x

T =7.7+2x

Also Krystal had a coupon worth $1.50, the cost of the ticket will be

T =(7.7+2x) - 1.50
