**Question: 130**

**20.** If it takes x widgets to make one thingumajig, and one thingumajig can produce y whatchamacallits, then the number of widgets needed to produce n whatchamacallits is

A.

B. nxy

C.

D.

E.

**Correct Answer:** A

**Explanation:**

A. To solve this problem, I'll pick pretty numbers and say that 10 widgets makes a thingumajig and that a thingumajig can produce 2 whatchamacallits. So it takes 5 widgets, or x/y, to make one whatchamacallit. To make n whatchamacallits, you have to multiply by n, which is what Choice (A) tells you to do.
