Answer:
17% off $35
Step-by-step explanation:
The reason I say 17% off $35 is better price is because you get $5.95 off the original price.
So how did you do it they wonder, well in order to find out how much we are going to be taking off of a number as a percentage we have to turn 17% and 12% into a decimal by multiplying 17% and 12% by 100.
17% * 100 = 0.17
12% * 100 = 0.12
Now we multiply 0.12 by $32 and 0.17 by $35 in order to find out how much money you are saving:
0.12 * $32 = $3.84
0.17 * $35 = $5.95
So since $5.59 is bigger than $3.84 you have your answer 17% off $35 is a better price.
So basically, the 2 is the y- intercept which means that is where your line starts. The 1/2 is the slope which means you make a dot every time you go up 1 and over 2
I don't know what the "six-step method" is, but I do know how to solve the problem:
Let x = number of gallons of 50% solution
amount of antifreeze in 50% solution = 0.50x
amount of antifreeze in 10% solution = 0.10(80) = 8
amount of 40% solution = 0.40(x+80) = 0.40x + 32
Then, 0.50x + 8 = 0.40x + 32
0.10x = 24
x = 240 gal
