Question

A bakery sells bags of cookies for $10. Different groups of children buy the cookies, with each group sharing the cost evenly among its members. The amount of money that each child in a group will pay depends on how many children are in that group. The function that relates the number of children in a group ( n ) and the amount that each one pays ( a ) is a = 10 n . Which of the following graphs shows this function?

Answer 1

The function that relates the number of children in a group (n) and the amount that each one pays (a) is given by:

a=10n

This is a linear function with a slope of 10 and a y-intercept of 0. The graph of this function is a straight line that passes through the origin (0, 0) and has a slope of 10. Therefore, the correct graph is Option B.
