Question

Jayden estimated the cost C=7n+350 for producing n items. If he sells each item for $12, how much money did Jayden think he was going to spend before he produced one item?

A. 7n+350
B. 12n−350
C. 12n+350
D. 7n−350

Answer 1

Before producing a single item, Jayden estimated he would spend 350 on costs. This is obtained from Jayden's cost equation C = 7n + 350 by setting n to 0, yielding C = 350. The correct answer is A. 7n + 350.

Step-by-step explanation:

Jayden estimated the cost C = 7n + 350 for producing n items. To find out how much Jayden thought he was going to spend before producing one item, we look at the cost equation when n = 0. Substituting n with 0 in the cost equation, we get:

C = 7(0) + 350

C = 0 + 350

C = 350

This means that before producing a single item, Jayden estimated he would spend 350. Therefore, the correct answer is A. 7n + 350, as the term 7n represents the variable cost which is zero when no items are produced, leaving only the fixed cost of 350.
