a group of friends went to lunch the bill sales tax and tip was 48.60 a sales tax of 7% was added the group then tipped 18% on the amount after the sales tax was added what was the amount in dollars of the sales tax(show the steps pls)

Answers

Answer:

Sales tax = $2.79

Step-by-step explanation:

(18 x 48.6) /100

= 8.748 = $8.75 tip amount total

48.60-8.748 = 39.852 sales total

(39.852 x 7)/100

= 2.78964 = $2.79 sales tax

39.852 - 2.78964 = 37.06236 = $37.06 cost of bill

Sales tax was asked = $2.79

-4x + 2 = -18

Answers

Answer:

x = 5

Step-by-step explanation:

-4x + 2 = -18

subtract 2 from both sides

-4x + 2 - 2 = -18 - 2

simplify

-4x = -20

divide both sides by -4

-4x/-4 = -20/-4

simplify

x = 5

Creed's brother earns $12.00 per hour. The store offers him a raise -- A 5% increase per hour. After the raise, how much will Creed's brother make per hour?

Answers

Answer:

$12.60

Step-by-step explanation:

Creed's brother originally makes $12.00 an hour. A 5% raise means that:

$12.00 × 1.05 = $12.60

If you raise $12.00 by 5% then you have the formula
12x0.005=0.006
12+0.6=12.6
So after the raise Creeds brother will make $12.60/hour
