Achalk board is marked up 150% from an original purchase cost of 80$ cara sold the chalkboard earning 14% commission on the sale price. how much commision did she make?

Hey! To do this, first we need to find our sale price. To do this. take the $80 and multiply it by 180% (1.8) because of the 80% markup and you get $144. Now, you need to find the commission. Take the $144 and multiply it by the 14% commission to get $20.16. Hope this helped!

step-by-step explanation:

21-4

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
