Answer: 7.2$
hope it helps :)
step-by-step explanation:
Cost of each box = 3$
Cost of 3 boxes without 20% coupon = 9$
With 20% off Coupon = 9 by 100 multiplied by 20
(the zero's cut with each other leaving)
= 9 by 10 multiplied by 2
(9 multiplied by 2 = 18)
= 18 by 10
(18 divided by 10 = 1.8)
= the 20% of 9$ is equal to 1.8
when subtracted with the total cost leaves 7.2$
Answer: 539 without defects
Step-by-step explanation: Im pretty sure we have to turn 12/320 into a percent, which is 0.0375, or 3.75%
So with that information, we need to find 3.75% of 560.
do 0.0375 x 560, which is 21.
21 are defects, so do 560 - 21 is 539.
