Answer:
$78, $79.20
Step-by-step explanation:
PART A: $60 times 1.3 = $78
you add 30% to 100% to get 130% since it is a mark up, and then you convert to a decimal by going to the left twice then multiplying by original price.
PART B
Since it is a discount you subtract 15 percent from 100, but then add back 5 percent since there is tax applied to get 90%, convert to decimal and multiply by original price to get $88 x .9 = $79.20
Hello from MrBillDoesMath!
Answer:
(3,6) is not a point of intersection of the lines.
Discussion:
Let's check if the supposed point of intersection, (3,6), is on both lines. Start by substituting x = 3 and y = 6 in the equation y = 4x -2. This gives
y = 4x - 2
6 = 4(3) - 2 = 12 -2 = 10
6 does not equal ten so the supposed point of intersection doesn't even lie on one of the lines! Hence (3,6) is not a point of intersection of the lines.
Thank you,
MrB
