Answer:
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 = $1.50
To Find :
Equation to determine crystals total bill (T) given the cost of one bag of chips = ?
Solution:
Let the cost of one chips bag be x
Cost of 4 bottles of pop
=>![4 \times 1.25](https://tex.z-dn.net/?f=4%20%5Ctimes%201.25)
=>$ 5
Cost of 3 candy bars
=>![3 \times 0.90](https://tex.z-dn.net/?f=3%20%5Ctimes%200.90)
=>$ 2.7
Cost of 2 bags of chips
=>![2 \times x](https://tex.z-dn.net/?f=2%20%5Ctimes%20x)
=>$ 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
