The total amount Jerom earned this weekend is $252.50.
The total amount is the sum of the amount Jerom earned from serving meals and sum of the amount Jerom earned every week.
Jerom earned eevery week = $80.
So the amount Jerom earned from serving meals is
$[tex] (252.50-80) [/tex] = $ [tex] 172.50 [/tex]
Jerom earned 15% of the cost of meals by serving them.
Let's take the total cost of the meals Jerom served this weekend be $x.
So the amount of money Jerom earned from serving meals is 15% of $x.
So 15% of $ x = $[tex] (x)(\frac{15}{100} ) [/tex] = $[tex] (\frac{15x}{100} ) [/tex]
We have got 15% of $x is equal to $172.50.
So we can write the equation as ,
[tex] \frac{15x}{100} = 172.50 [/tex]
Now to get x, we have to move 100 to the right side by multiplying it to both sides. We will get,
[tex] (\frac{15x}{100})(100) = (172.50)(100) [/tex]
[tex] 15x = (172.50)(100) [/tex]
[tex] 15x = 17250 [/tex]
Now to find x, we have to move 15 to the other side by dividing it to both sides. We will get,
[tex] \frac{15x}{15} = \frac{17250}{15} [/tex]
[tex] x = 1150 [/tex]
So we have got the required answer. The amount of meals Jerom served this weekend is $1150.
