47.99 divided by 100 is 0.4799 if we times that by 106 to give us the total price with sales tax added on we will get 50.70 then if we divide that by 5 to get 20% we will have 10.14 if we times that by 4 we will have our answer which is.......$40.56
First calculate what the coupon does for Camille so multiply %20 by the cost or .2(47.99)=9.598 which rounds to 9.60 meaning she still paid $38.39 Then calculate sales tax by multiplying her clearance price by %6 and adding it on the cost .06(38.39)= 2.3034 which rounds to $2.30 in tax. Add that onto the clearance price 38.39+2.30=$40.69 <span>So her total cost was $40.69</span>
Perpendicular means it’s opposite reciprocals for example : the slope is 2 then the perpendicular line’s slope would be -1/2 because it flips the number also makes it the opposite sign.
