Hope this helps

7. 100

8. 14

9. 12600

10. 639

11. 128

12. 399

13. Discount price= 12.87 Sale price= 26.13

14. 40.80

15. 12,750

I'm not 100% on #15 but the rest are good.

Step-by-step explanation: When you multiply the percent by the other number that gives you the difference. So then get the original number and either add or subtract the difference from the original number to get your answer. Add if increase Subtract if decrease.

So 7-11 you just have to multiply the percent by the other number.

7. 25*300% or 25*3 = 75  25 + 75 = 100

8. 56*.75 = 42  56-42= 14

9. 12000*.05 = 600 (since it is an increase add 600 to 12000) = 12600

10. 710*.10= 71 (71 is the difference so do this) 710-71= 639

11. 160*.20 = 32 (decrease) 160-32= 128

12. 380*.05=19 (increase) 380+19 = 399

13. 39*.33= 12.87 (decrease)

Discount price = 12.87

Sale price= 39-12.87= 26.13

14. 48*.15 = 7.20 (decrease) 48-7.20= 40.80

15. 3,000*3.25 = 9750 (increase) 9750 + 3000= 12,750

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
