Answer:
An equation where the two companies would be the same is given as:
25 + 3.50x = 17 + 7.50x
Step-by-step explanation:
Let the number of trophies ordered be represented by x
Maria is ordering trophies for school. Company Christopher charges $3.50 for each trophy and a one-time engraving fee of $25.
$25 + $3.50 × x
25 + 3.50x
Company Asya charges $7.50 for each trophy and a one-time engraving fee of $17
$17 + $7.50× x
17 + 7.50x
An equation where the two companies would be the same is given as:
Company Christopher = Company Asya
25 + 3.50x = 17 + 7.50x
Simplifying further:
Collect like terms
25 - 17 = 7.50x - 3.50x
8 = 4.00x
x = 8/4
x = 4
Hence, the two companies would be the same after 4 trophies.

Step-by-step explanation:
----------------------------------------------
Calculate Jean's rate
----------------------------------------------
Jean takes 8 hours to fill the pool.
So in 1 hour, she can fill 1/8 of the pool
----------------------------------------------
Calculate Mark's rate
----------------------------------------------
Mark takes 12 hours to fill the pool.
So in 1 hour, he can fill 1/12 of the pool.
----------------------------------------------
Calculate their rate if they work together
----------------------------------------------
Jean = 1/8
Mark = 1/12
1/8 + 1/12 = 3/24 + 2/24 = 5/24
They will fill 5/24 of the pool in 1 hour
----------------------------------------------
Find number of hours needed to fill up the pool
----------------------------------------------
I hour = 5/24 of the pool
1 ÷ 5/24 hour = 5/24 ÷ 5/24 of the pool
24/5 hour = Whole pool
Whole pool = 24/5 hours
Whole pool = 4 4/5 hours or 4.8 hours
----------------------------------------------
Ans: The supervisor is not correct, it will take only 4.8 hours if both of them work together.
