Molly's equation
15x + 10 = 100
-10 -10
15x=90
/15 /15
x=6
Maddie's equation
15x - 10 = 100
+10 +10
15x=110
/15 /15
x=7 1/3

Step-by-step explanation:

If there is 2 field trips with 23 students and each student costs $5 dollars. So for the 1st trip it will be 23x$5
1st trip- $115
And on the second trip its the same because there is 23 students that cost 5 dollars so it will be 23x5
2nd trip- $115
To find out the total of both trips youd add 115+115/
In total, for both trips it will cost $230 dollars.
