Question

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?

Answer 1

Each month the price increases by $0.04. After 39 increases (from month 1 to month 40):

Price = $1.25 + 39 × $0.04 = $1.25 + $1.56 = $2.81.

So the cantaloupe will cost $2.81 in the 40th month.
