There is an invitation fee to join the pine river country club, as well as monthly dues. the total cost after 7 months membership will be $3,125, and after 1.5 years, $4,060. find both the intuition fee and monthly dues

1.5 year is also 17 months. so 4060-3125=935 which equals 10 months, then 935÷10=93.5 which gives us the monthly dues. Then 93.5×7=654.5 which gives us the total of monthly dues for 7 months without the intuition fee. Then 3125-654.5=2470.5 that gives us the intuition fee.

Step-by-step explanation:

we know that

The volume of the figure is equal to the volume of cube plus the volume of the cylinder

step 1

Find the volume of the cube

The volume of the cube is equal to

we have

----> the length side of the cube is equal to the diameter of the cylinder

so

step 2

Find the volume of the cylinder

The volume of the cylinder is equal to

we have

substitute

step 3

The volume of the figure is equal to
