The movie theater took in $1,174 one Monday night. The number of $7 child tickets was ten more than twice the number of $9 adult tickets. How many of each were sold? child tickets :
adult tickets :

Adult tickets:48

Child tickets:106

Step-by-step explanation:

7(2a + 10) + 9A = 1174                  A = Adult tickets

14a + 70 + 9a = 1174                     C = Child tickets

23a + 70 = 1174

23a + 70 - 70 = 1174 - 70

23a/23 = 1104/23

A = 48

C = 48(2) + 10

C = 96 + 10 = 106

c

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
