Question

Use compatible numbers to estimate the following: Mark bought a digital camera for $148.65. If this amount was to be split between three people who are using the camera, estimate the amount each would pay using compatible numbers.

Answer 1

Not sure if I understand your question correctly, but:
If all three would pay the same price, so you have uniform distribution, then you each person would pay one third of the total price. (1/3)*148.65 = 148.65/3
