Answer:
$325
Step-by-step explanation:
Time-share = $10 500
On first $10 000
,
Commission at 3 % = 0.03 × 10 000 = $300
On remaining $500,
Commission at 5 % = 0.05 × 500 = <u> 25
</u>
Total commission = $325
Frank made $325 selling the time-share.

Multiply both sides by 11.

Divide both sides by 7.
f = 1
