The price of a cantaloupe at a fruit stand goes up 4 cents each month. The first month the stand was open, a cantaloupe cost $1.25.

What will the cost of a cantaloupe be in the 40th month?

In 1 month, cost goes up 4 cents.

then, In 40 months cost goes up 40 × 4 = 160cents.

Cost in 1st month = $1.25

so, cost in 40th month = $160 + $1.25

= $161.25

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,
