A school sponsors a competition for 78 students. The students work a total of 8970 math problems in 4 hrs. Each student works the same number of problems how many problems does each student work

answer

115 problems

explanation

since each student works out the same number of problems, you want to divide (total problems)/(students) to get the problems per student

the 4 hours is irrelevant here

total problems / students

= 8970 / 78

= 115 problems

the linear relationship that represents a variation in direct proportion is the linear function that varies according to the numbers of its domain, for example the cost of producing x number of items can be represented in direct proportion by f (x) = mx + b, where m is the constant of proportionality, x the number of articles produced and b the fixed cost
