Mrs. Samuelson had $350 to spend on a field trip for herself and 18 students. Admission was $12.50 per person and lunch cost about $5.00 per person. Write an equation to describe the amount of money left after the trip.

Step-by-step explanation:

Answer is $17.5

It says Mrs. Samuelson had $350 to spend on a field trip for herself and 18 students. so there are 19 people. Multiply 12.50*19 you get 237.5.

It also says lunch cost about $5.00 per person. Multiply 5.00*19 you get 95.

Add 95 to 237.5.

You get 332.5

Subtract 350 by 332.5.

Equation: 350 - (19*12.50) + (19*5.00)

Answer: $17.5
