Solve the equation . algebra ii double points
0.25% - 0.125 + 0.51 =0.5+r
show your steps and explain your work. tia : )

Step-by-step explanation:

0.25r-0.125+0.5r=0.5+r

0.25r + 0.5r - 0.125 = 0.5 * r

0.75r - r = 0.125 + 0.5

-0.25r = 0.625

r = 0.625 / -0.25

r = -2.5

step-by-step explanation:

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
