y= (-5/2)x - 22
because 5x+2y=12 turns to y=(-5/2)x + 6 and the line parallel to it has to have the same slope so you have to just get the y intercept by plugging in -10 into the equation (-5/2)(-10)+?=3 and ?= -22.
Answer:
132-110(the original price)= 22
Step-by-step explanation:
114+18=132
Because you would add 20% to 100% which makes it 120% and then you would solve like any other percent. Thus getting 110 as the original price.
f(x) = 10x + 50
multiply the cost per person by 5 ( you and 4 friends )
f(x) = 5(2x + 10) = 10x + 50
