Answer:
$9500
Step-by-step explanation:
Given, Option A: Hourly wage is $19 and the salesperson works 40 hours per week. So, he will earn in a week= 19 X 40 = $760
Now, according to option b, he will get 8% commission on weekly sales.
Let. x = the amount of weekly sales.
To earn the same amount of option A, he will have to equal the 8% of x to $760
So, 8x/100= 760
Or, 8x= 76000
Or, x= 76000/8= 9,500
the salesman needs to make a weekly sales of $9,500 to earn the same amount with two options.
Compare 100 to 110, and see that to go from 100 to 110 is a 10% increase, but to go from 110 back down to 100 is a 9.09% decrease not a 10% decrease
