Question 27 • AZ-Algebra 1A (MA101)

Layla deposits at least 25% but no more than 50% of her paycheck into a savings account. If she earns $200 per paycheck, which statements about the amount of money she deposits, s, are true? Check all that apply.

Answer
A
25 ≤ s ≤ 50
B
50 ≤ s ≤ 100
C
s ≤ 25 or s ≥ 50
D
s ≤ 50 or s ≥ 100
E
She could deposit $50.
F
She could deposit $75.

Explanation

Find 25% and 50% of $200: 0.25 × 200 = $50 and 0.50 × 200 = $100. So Layla can deposit any amount from $50 through $100, inclusive, making B true. She could deposit $50 or $75, so E and F are also true.
