There are no constants here. But we have x and y here.
We will create an equation which is:
2y+3x=54.
But we will also create a second equation which states the number of seats.
x+y=24.
Now we do the two-equation solving method.
2y+3x=54
-2(x+y=24)
2y+3x=54
-2x-2y=-48
x=6
To solve for y, plug in x into one of the original equations. Which one doesn't matter.
y+6=24
y=18
$2.99 + 7% of $2.99 =
= $2.99 + 7% * $2.99
= $2.99 + 0.07 * $2.99
= $2.99 + $0.21
= $3.20
Answer:
Step-by-step explanation:
you ate 3
you paid $9.45 for the 3
to find the cost of the whole pizza you need to know how much each slice costs so
9.45 / 3 = $3.15 a slice
so each slice is $3.15 and there are 8 slices and you need to know how much they cost altogether so
3.15 * 8 = $25.20
