John is going camping, and he needs to buy a tent. The outdoor store has one that cost $90, but it's on sale for 25% off. What is the sale price? * A.$22.50 B.$65.00
C.$67.50
B.$112.50

C. $67.50

Explanation:

1. Convert 25% into a decimal (0.25)

2. Multiply 90 by 0.25 to get the amount of money discounted. (90x0.25=22.5=$22.50)

3. Subtract 22.5 from 90 to get the sales price. (90-22.5=67.5=$67.50)

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
