Question

a mail-order company charges $12 for each t-shirt. Shipping costs $5 per order. Write a variable expression for the cost of ordering x number of t-shirts.

Answer 1

The variable expression for the total cost of ordering x number of t-shirts, with each costing $12 and a shipping fee of $5 per order, is 12x + 5.

Step-by-step explanation:

The cost of ordering x number of t-shirts from a mail-order company can be expressed as a variable expression. Given that each t-shirt costs $12 and the shipping cost per order is $5, the total cost would be the sum of the cost of the t-shirts and the shipping fee. Therefore, the variable expression is 12x + 5, where x represents the number of t-shirts ordered.

The variable expression for the cost of ordering x number of t-shirts from the mail-order company, where each t-shirt costs $12 and there's a flat shipping fee of $5 per order, is:

Cost

=12+5

Cost=12x+5

Here:

x represents the number of t-shirts ordered.

12x is the cost of the t-shirts at $12 per t-shirt.

5

5 is the flat shipping fee per order.

This expression calculates the total cost, combining the cost of the t-shirts and the shipping fee for the given quantity of t-shirts.
