Steve sells vacuum cleaners door to door. He earns a base salary of $500 plus $100 for every vacuum cleaner he sells. Steve also works selling encyclopedias door to door. He makes $300 plus $200 for every set of encyclopedias he sells. How many items would Steve need to sell for the two salaries to be the same?

2

Step-by-step explanation:

Let x = number of items Steve sells

Let y = salary earned

Create two equations:

Vacuum sales:  y = 500 + 100x

Encyclopedia sales: y = 300 + 200x

Equal the equations and solve for x to find the number of items Steve needs to sell for the two salaries to be the same:

500 + 100x = 300 + 200x

Subtract 300 from both sides:  200 + 100x = 200x

Subtract 100x from both sides: 200 = 100x

Divide both sides by 100:  2 = x

Therefore, Steve would have to sell 2 items for the two salaries to be the same.

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
