The art club decides to sell calendars as a fundraiser. The initial cost to make the calendars is $605 for equipment with an additional materials cost
of $2.50 per calendar. If the club plans to sell the calendars for at least $8
a piece, how many would they need to sell to break even?

I got 106 calendars

Step-by-step explanation:

605 divided by 2.50 = 242. Next you have to add what you got to the initial cost. Then we get 847. Next you have to divide this by 8 and round up, and i got 106. I might be wrong XD

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,

answer4 to the second power is 16

and 4 to the third power is 64,
