Question

20 POINTS Compost costs $10 per cubic yard and topsoil costs $2 per cubic yard. Maria needs more than 10 cubic feet of topsoil. She can spend no more than $50. The graph below represents the amount of each she can buy.
Which amounts of materials satisfy the relationship?
2 cubic yards of compost, 8 cubic yards of topsoil
4 cubic yards of compost, 5 cubic yards of topsoil
1 cubic yard of compost, 12 cubic yards of topsoil
3 cubic yards of compost, 12 cubic yards of topsoil

Answer 1

I can't see the graph but let's use logic
hmm, more than 10 cubic feet of topsoil so the first and 2nd options are wrong

let's ee the costs
3rd option
10*1=10
2*12=24
10+24=34 and 34<50, that is fine

4th option
3*10=30
2*12=24
30+24=54
54>50, nope, that is over cost


answer is 3rd one
the one with 1 cubic yard compost and 12 cubic yard topsoil
