Mustafa’s soccer team is planning a school dance as a fundraiser. The DJ charges $200 and decorations cost $100. The team decides to charge each student $5.00 to attend the dance. If n represents the number of students attending the dance, which equation can be used to find the number of students needed to make $1,500 in profit?

A
5n – 300 = 1,500
B
5n + 300 = 1,500
C
5n – 200 + 100n = 1,500
D
5n – 100 – 200n = 1,500

The Allied Taxi Company charges $2.50 to pick up a passenger and then adds $1.95 per mile. Isaac was charged $27.46 to go from one city to another. If x represents the number of miles driven by the taxi, which linear equation can be used to solve this problem, and how many miles did Isaac travel, rounded to the nearest tenth?

A
1.95x + 2.50 = 27.46; Isaac traveled 15.4 miles.
B
1.95x + 2.50 = 27.46; Isaac traveled 12.8 miles.
C
2.50x + 1.95 = 27.46; Isaac traveled 11.8 miles.
D
2.50x + 1.95 = 27.46; Isaac traveled 10.2 miles.
