The cost of pizza is dependent on the number of toppings, so number of toppings is the independent variable.
The Area If triangle = 1/2 x 5 x 8
3 / (y - 2) = 8....multiply both sides by (y - 2), eliminating it on the left side
3 = 8(y - 2)
3 = 8y - 16
3 + 16 = 8y
19 = 8y
19/8 = y
2 3/8 = y <==
6(4j - 6)
Distributing,
6(4j) - 6(6)
24j - 36
which is not equivalent to 24 - 36j
You can spend about 3.54 per square ft.
In order to find this we will need to figure out how many square ft. there are exactly. We can do this by doing 20 x 12, which is 240. Now, to figure how much we could spend per square ft., we would have to do 850 / 240, which is(rounded) 3.54.
