Bob is making mini fondant cakes for next bake sale each cake costs bob $1.80 to make if he sells the cakes for $3.00 each how many will he have to sell to make a profit of exactly $36.00 me answer

he would have to sell 30 cakes

Step-by-step explanation:

if you take the amount it actually cost to make it and the amount he is selling them for you would first do

1.80 - 3.00 = 1.20$

after you get 1 dollar and 20 cents you would divide it by 36 dollars to get 30

to check your answer do 30 x 1.20 = 36.00

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
