Question

Translate the following phrase into an algebraic expression using the variable x. Do not simplify,

the cost of x textbooks if one textbook costs $127

Answer 1

127x

Explanation:

The expression 127x will represent this situation.

Since x represents the number of textbooks, we can put the coefficient 127 in front of it to include the cost.

For example, 2 textbooks will be $254 if we plug in 2 as x into the expression, since 127(2) = 254.
