A grade 7 class is going on a field trip to the Science Centre. The cost of the bus is $250. It costs $10 per student for admission, and an additional $7 per student to attend a session on Heat Transfer. Write an expression to represent the total cost and determine how much it will cost if 60 students attend.
$250 is the independent value, so we start the equation with $250, and since there are 60 students and the $10 and $7 costs are per student, you multiply the values, giving you a final equation of: 250+10(60)+7(60)= $1,270
