Which equation matches the following situation? 331 students went on a field trip. Six buses were filled and 7 students traveled in cars. How many students were in each bus?

• n= # of students in each bus; 6n + 7 =331

• n=# of buses; 6n + 7 =331

April had $24 to spend on seven pencils. After buying them she had $10. How much did each pencil cost?

• n=total cost pencils; 7n+10=24

• n=cost of 1 pencil; 7n-10=24

• n=cost of 1 pencil; 7n+10=24

• n=cost of 1 pencil; -7n-10=24

The space club is having some posters printed. The printer charges $250 plus $2 per poster. How can I figure out how many posters I could print for $1,000?

• 250x + 2 = 1000

• 1000 + 2x = 250

• 250 - 2x = 1000

• 2x + 250 = 1000
