Question

Would someone be so kind as to lend a helping hand to me in solving this question?

Answer 1

Answer:
a) Provider B would be cheaper
b)
`10m^3`

Explanation:
a) Input 6 into both equations and solve. For Provider A, it would go like this:
`y = 6 + 15`. For Provider B, it would be this:
`y = 2(6) + 5`. The first provider adds up to £21 Pounds ($25.56 USD). The second provider adds up to £17 Pounds ($20.69 USD).

b) All you really need to do is just plug in numbers until both equations contain the same answer. The way I did it was:
`x + 15 = 2x + 5`. If your teacher asks how you got the answer, follow these steps:

`x+15=2x+5\\x-5=2x-5\\x+10=2x`
