Answer:
0.3[x-2y] + 0.5x - y
Use the distributive property: a(b-c) = ab - ac
0.3x - 0.6y + 0.5x - y
Now, add/subtract all like terms
0.3x + 0.5x - 0.6y - y
0.8x - 1.6y
If you want, we can simplify that down further to:
0.8(x - 2y)
the rate for 5 cans for $3.70 is 0.74
the rate for 10 cans for $4.10 is 0.41
so the better buy is 10 cans for $4.10 at sams
The correct answer would be 3.65.
