Question No 47

You can earn 15n dollars for mowing n lawns. How much do you earn for mowing 1 lawn? 7 lawn?

Money earned for mowing n lawns = 15 n

Money earned for mowing 1 lawn:

Put n = 1 in the equation:

`15 n\\=15(1)\\=15`

So, Money earned for mowing 1 lawns = 15 dollars

Money earned for mowing 7 lawn:

Put n = 7 in the equation:

`15 n\\=15(7)\\=105`

So, Money earned for mowing 7 lawns = 105 dollars
