Answer:
The cost of each pack of bottle = x = $0.91
Step-by-step explanation:
Let 'x' be the cost of one pack of a juice bottle
so the cost of 4-pack of juice bottles = 4x
The total cost of a bag of apples = $1.85
Given that the total cost of a bag of apples and 4-pack of juice bottles before tax = $5.49
Thus, the equation becomes
1.85 + 4x = 5.49
4x = 5.49 - 1.85
4x = 3.64
Divide both sides by 4
4x/4 = 3.64/4
x = 0.91
Thus,
The cost of each pack of bottle = x = $0.91
VERIFICATION
As there are 4 packs of juice bottles and each pack costs = x = $0.91
so 4-packs of bottle = 4x = 4(0.91) = $3.64
cost of a bag of apples = $1.85
Thus, total cost:
$1.85 + $3.64 =$ 5.49
