Susan had $50\$50 to spend at the carnival. She spent $12\$12 on food and twice as much on rides. How many dollars did she have left to spend?
12 12
14 14
26 26
38 38
50 50
Answer: B
Concepts:money
Small hint:
Find how much Susan spent on rides before subtracting from 50.50.
Big hint:
Twice as much as $12\$12 is $24\$24.
Solution:
Susan spent 2⋅12=242\cdot 12=24 dollars on rides, so she spent 12+24=3612+24=36 dollars total.
She had 50−36=1450-36=14 dollars left.
Thus, B is the correct answer.
