Alex went to the store to buy supplies for peanut butter and jelly sandwiches for his birthday party. He bought bread for $3.29 for each loaf, peanut butter for $2.99 per jar and jars of jelly. The total cost was $23.64. If Alex bought three of each item, what was the cost of one jar of jelly? 1. Define the variable. =
2. Equation to be solved =
3. One jar of jelly cost =

Define the variable: The variable is the cost of one jar of jelly

Equation to be solved: Refer to Step by Step

One jar of jelly cost: 1.60

Step-by-step explanation:

total bread cost: 9.87

total peanut butter cost: 8.97

total jelly cost: x

so 23.64 - (9.87 + 8.97) = x

simplified: 23.64 - 18.84 = x

even more simplified: 4.80 = x

so 3 jars of jelly is 4.80

so divide

4.80 divided by 3 = 1.6

so one jar of jelly costs 1.6

d? maybe

step-by-step explanation:

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
