semir, sarah and sung so decided to raise money for a local homeless shelter by working in a local deli. the deli agreed to donate to the shelter a portion of the profits from each meal the three sold. semir sold 3 times as many meals as sarah. sung sold 2 more meals than sarah.
wtire an expression for the number of meals that each sold?
???? I don't know how many sarah sold. Im confused on getting an expression.
x=semir
y=sarah
z=sung
semir sold 3 times as many meals as sarah
x=3*y
sung sold 2 more meals than sarah.
z=2+y
y=y
so
3*y + y + (2+y) = meals sold
you can simplify more
3y+2y+2
let sarah's sales be x
then semir sold 3x
and sung sold x+2
3y+2y+2
I don't understand what was the answer to the total of their sales.
3y+y+2y
To create an expression for the number of meals each person sold, let's define a variable for Sarah's number of meals.
Let's say Sarah sold x meals.
Based on the information given:
- Semir sold three times as many meals as Sarah, so Semir sold 3x meals.
- Sung sold two more meals than Sarah, so Sung sold x + 2 meals.
Therefore, the expression for the number of meals each person sold is:
- Semir: 3x
- Sarah: x
- Sung: x + 2
Note: Since it was not specified how many meals Sarah sold, we used the variable x to represent this unknown quantity.
