Question

Joey is ordering pet food online. To qualify for free shipping he needs to spend at least $100.

He already has $12 worth of treats in his cart.
Write and solve an inequality to find how many bags of food at $22 each he needs to order to
qualify for free shipping.

Answer 1

Atleast 4 bags

Explanation:

Let's use "x" to represent the number of bags of pet food Joey needs to order.

Since each bag of food costs $22, the cost of "x" bags of pet food will be 22x dollars.

We know that Joey already has $12 worth of treats in his cart, so the total cost of his order will be:

22x + 12

To qualify for free shipping, Joey needs to spend at least $100, so we can set up the following inequality:

22x + 12 ≥ 100

Subtracting 12 from both sides, we get:

22x ≥ 88

Dividing both sides by 22, we get:

x ≥ 4

Therefore, Joey needs to order at least 4 bags of pet food to qualify for free shipping.
