Answer:
$438.4
Step-by-step explanation:
According to question commission of Alice is composed of fixed part which is 5% of her first 4000 sales
and 8% on all sales over $4,000
Alice's total sale = $6,980
value of sale above 4000 = $6,980 - $4,000 = 2,980
now commission for first 4000 sales = 5% of 4000 = 0.05* 4000 = $200
commission for remaining sales = 8% of 2,980 = $238.4
Total commission of Alice = $200 + $238.4 = $438.4
