Step-by-step explanation:
9 nachos where sold the ratio would be 9:12
We can use algebra.
So, what rate time 1.20 = .80
Let x = the rate (in a decimal form)
1.20x = .80
x = .6666666666
Now, we need to multiply by 100 to get a percentage.
66.66 The price is 66% of the regular price.
They marked it off
33.33%
You would just do 4 x 7, which means there are 28 combinations.
12^3 = 1728; 14^3 = 2744;
