Gregory sees an $80.00 jacket on sale at 30% off. How much will it cost after a 7% sales tax is applied? $56.00 $59.92 $64.00 $67.43

Step-by-step explanation:

The jacket is 30% off which means the sale price is 70% of the original cost.

Multiply the original price by 70%:

80 x 0.70 = $56.00

Now multiply the sale price by 1 + sales tax:

56 x 1.07 = $59.92

I HOPE THIS HELPS! :)

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
