Kalvin sells bottles of water at baseball games. He pays $0.75 per bottle and $3.78 for the ice to keep the water cold. Let b represent the number of bottles of water he buys and C represent his total cost.
Which equation shows the relationship between his total cost and the number of bottles?
O A C = b +0.75
OB. C = b +3.78
OC. C = 0.75b +3.78
OD. C = 3.785 +0.75

ask the math teacher she or he would know lol.

step-by-step explanation:

ιт ιѕ 6/23

step-by-step explanation:

нσρє ι ¢συℓ∂ нєℓρ!

one way is to plot 2 points and connect them which is what the answer choices seem to be doing

it seems to be using the y intercept and the slope

y=mx+b, m=slope, b=y-intercept (where the line hits the y axis)

slope=rise/run

y-intercept is where the line croses the y axis which is the y value where x=0

you seem to have given the wrong slope (you didn't put a number in front of te x, it should be 2/3 or 3/2 looking at the answer options)

y=? x-1

m=? because of your fault

b=-1

so it has a slope of ? and y intercept of -1, meaning it pases through (0,-1)

so draw point (0,-1) (so answer is one of the first 2 option)

if slope is 2/3, then go up 2 and right 3 then draw line through those 2 points

if slope is 3/2, then go up 3 and right 2 then draw line through those 2 points

good luck on ur quiz test or homework. have a good day : )
