Question

Anna saved $20 in a jar each month for 2/1/2 years. She spent 75% of her savings on a computer. How much money did Anna have left in the jar? A $150 B $240 C $450 D $600

Answer 1

2 and 1/2 years = 30 months

$20 \times 30 = 600$
$100\% - 75\% = 25\%$
$600 \times 25\% = 150$
The answer is A. $150

Hope this helps.
