Question

Lucy bought snacks for her team's practice. She bought a bag of apples for $1.85 and a 4-pack of juice bottles. The total cost before tax was $5.49. Write and solve an equation which can be used to determine x x, how much each bottle of juice costs? Equation: Answer: x x =

Answer 1

Equation: 4x+1.85=5.49

Answer: x = 0.91

Answer 2

The cost of each pack of bottle = x = $0.91

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
