The first step to solving this problem is to write an equation to express the parameters of the problem. The equation is expressed as this:

You can arrive at this equation by taking the ratio of 2 bike rentals and 1 skate rental and adding up the sum of all the purchases.

This makes x equal to making 2 bike rentals and 1 skate rental. If we solve the original equation for x, the result is 5.838. Since we need to be above 362 dollars, we can round up to x = 6. This translates to 12 bike rentals and 6 skate rentals. Finally, we arrive at the answer of 6 skate rentals.
I hope you do not intend some sort of compounding.
Basically, 3000 per month for 40 years can be calculated by doing some simple maths. So 3000 x 12 to get for a complete year. Which is 36000. NOw we can multiply this value by 40 to get the correct amount. So that is 1440000.
Now five percent of this amount is 5 / 100 x 1440000 = 72000. So the final answer after adding 5 % would be 1512000.
