Is this a simultaneous equation question?
Answer:
15 and 12
Step-by-step explanation:
Set the two sides as x and y
y=x-3
P = 2w+2l
2x+2(x-3) = 54
4x-6=54
4x=60
x=15
y=12
We want to increase by 15% so we want 100% plus 15% which means 115%
Since we want 115% lets make the calc:
65 pizzas ----------- 100%
x pizzas ------------- 115%
Multiply in cross
65 . 115 = 100.x
7475 = 100.x
x = 74,75
Since we cant sell 74 pizzas and 0,75 pizza we will sell 75 pizzas
So we need to sell 75 pizzas to employees receive the bonus
