➷ Just multiply the price by 3:
1.35 x 3 = 4.05
It would cost $4.05

First one is 7.73 (23.19/3)
Second one is 14.04 ((19.71/7.3) x 5.2)
Here is a sample problem
has to be perpendicular to y=(4/9)*x-2 and pass through 4,3,
y-b=m(x-a)
slope of -9/4 is perpendicular to slope of 4/9, as y=4/9x-2 has slope 4/9. Our point is (4,3) therefore.
y-3=-9/4*(x-4)
y-3=-9/4x+9
y=-9/4x+9+3
y=-9/4x+12
The answer is 0.04444... or 2/45. Whichever is more useful to you.
