Question

It takes 78 days to create a custom motorcycle. Write an algebraic expression to describe the number of days it takes to create n custom motorcycles. How many days will it take to create 6 custom motorcycles?
A) 78 + n; 84 days
B) 78 + 78n; 546 days
C) 78n; 468 days
D) 78⁄n; 13 days

Answer 1

The answer can be c or a

Answer 2

Answer is C

Explanation:
If it takes 78 days to create just one motorcycle, then:
78 days = 1 motorcycle
(78 × 2) days = 2 motorcycles
(78 × 3) days = 3 motorcycles and so on

This implies that the expression for the above statement is (78 × n) days. Also the same as 78n. Therefore, it'll take (78 × 6) days to create 6 custom motorcycles. The answer is hence 468 days.
