Harper sells appliances. She makes a weekly salary of $450 plus 3% commission on her total sales for the week. If her sales this past week were $3,200, find her total earnings for the week.

The total earning for the week is $546

Step-by-step explanation:

Let us solve the question

∵ Harper sells appliances

∵ She makes a weekly salary of $450 plus a 3% commission on her

   total sales for the week

→ That means there is a fixed amount + amount depends on her sales

∴ Her total earning = 450 + 3% of total sales

∵ 3% = 3/100 = 0.03

∴ Her total earning = 450 + 0.03 (total sales)

∵ Her total sales this week were $3,200

→ Substitute it in the equation above

∴  Her total earning = 450 + 0.03(3,200)

∴ Her total earning = 450 + 96

∴  Her total earning = 546

∴ The total earning for the week is $546

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
