Write an equation to illustrate the relationship between the amount of candy and the cost.

Given that the cost of a candy is 89 cents and you want to find the price or the amount.

let C(x) be the cost of a candy,

and x be the amount of candy

since on candy is equal to 89 cents

then c(x)=0.89x

but lets say a fixed tax of 20% of the price of candies then the equation will be

c(x)=0.89x+0.178x

where 0.178x is the product of 0.89, 20% of 0.89 and x.

the answer is c just got it on ed

step-by-step explanation:

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
