A landscaping company charges a flat rate of $50, plus $15 per acre. John wants a price quote on the cost of yard work for his plot of land.
Which expressions represent the cost of servicing x acres of John's land?
Select all that apply.
$50+$15x
$15x
$50−$15x
$75x
Well, John is lucky that the landscaping company doesn't charge per blade of grass!
Anyway, the correct expressions that represent the cost of servicing x acres of John's land are:
$50 + $15x
and
$15x
So, John can choose between the flat rate plus $15 per acre or just $15 per acre. Simple enough, huh?
The expressions that represent the cost of servicing x acres of John's land are:
$50 + $15x
$15x
To determine the cost of servicing x acres of John's land, we need to consider the flat rate of $50 and the additional charge of $15 per acre.
The expression $50 represents the flat rate of $50.
The expression $15x represents the additional charge of $15 per acre, multiplied by the number of acres (x).
Therefore, the expressions that represent the cost of servicing x acres of John's land are:
$50 + $15x
$15x
The expression $50 - $15x does not represent the cost of servicing x acres since it subtracts the additional charge of $15x from the flat rate, which does not make sense in this context.
The expression $75x is incorrect because it adds the flat rate of $50 and the additional charge of $15 per acre twice. It overestimates the cost.
So, the correct expressions are:
$50 + $15x
$15x
