Answer:
A student bought two juice pouches for $1.25 each and 3 bags of chips. The total cost was $5.05. Write and solve an equation to determine the cost of a bag of chips:
2(1.25)+3x=5.05
2.5+3x=5.05
3x=2.55
x=0.85
2) Four brothers each bought two hot dogs and a bag of chips at the football concession stand. If the bag of chips was 1.25, and the total was 18.20, what was the price of one hot dog?
One brother:
One brother = 2 hot dogs + 1 bag of chips
Four brothers:
Four brothers = 4 x (2 hot dogs + 1 bag of chips)
Four brothers = 8 hot dogs + 4 bag of chips
Given that they paid $18.20:
8 hot dogs + 4 bag of chips = $18.20
Given that the bag of chips is $1.25:
8 hot dogs + 4 ($1.25) = $18.20
8 hot dogs + $5 = $18.20
8 hot dogs = $13.20
1 hot dog = 13.2 ÷ 8 = $1.65
Answer: 1 hot dog = $1.65

6) Mrs. Johnson just purchased a total of 12 books and magazines for her office. the total bill was $112. she spent $16 on magazines and the book cost $12 each. how many book did she guy?
To do this problem, we can right an equation assuming the number of booked she bought is x:
16 + 12x = 112
First we will isolate the variable by subtracting 16 from both sides:
12x = 96
Then we will divide each side by 12:
x = 8
Since the number of books she bought is x, that must mean that:
Mrs. Johnson bought 8 books.
I HOPE THIS HELPS!!
