Phil and matt make cookies for a fundraiser at their school
Ivahew [28]
The equation would be y=0.45x.

Let x be the number of cookies Matt made.  Since Phil made 25% more, and 100%+25%=125%=125/100=1.25, the number of cookies Phil made can be represented by 1.25x.

Together the cookies they made are represented by x+1.25x=2.25x

Since there were 20% of the cookies remaining, this means they sold 100%-20%=80%=80/100=0.8 of the cookies:
0.8(2.25x) = 1.8x

Each cookie sold for 0.25, so we have
0.25(1.8x) = 0.45x

Letting y be the money they make, we have
0.45x=y

Multiplying fraction (2 1/2)(3 1/5)=
eduard
First you make the fractions top heavy instead of mixed numbers, so:
5/2 × 16/5
Then you just multiply across:
5 × 16 = 80
2 × 5 = 10
Your answer is 80/10, which can be simplified to 8.
