The number of dimes is three less than four times the number of quarters. If q represents the number of quarters, what expression gives the number of dimes?
A3 - 4q
B4q + 3
C4q - 3
D4(q - 3)
Answer & Solution
Correct answer: C. 4q - 3
1. The phrase three less than four times the number of quarters starts with four times q, or 4q.
2. Three less than that quantity means three is subtracted from 4q.
3. Writing three subtracted from 4q as algebra gives 4q minus 3.
