Step-by-step explanation:

Ms Annand spent $33 at the store. She bought 6 new white boards and 3 packs of Expo markers. The white boards cost $2 less than a pack of expo marker.

Our calculation is given below;

How much money did she spend on the white boards? How much money did she spent on the Expo markers?

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
