CPM Homework Help : MC1 Problem 1-82

Ramon is saving $\$7.75$ per week to buy a new cell phone. The model that he has in mind costs $\$125.00$ . Estimate the number of weeks that he will need to save, and then figure out the actual number of weeks.

Hint:

Remember that your estimate could be a natural, or counting, number such as $1,2,3,4$ ... Try rounding $\$7.75$ up and $\$125.00$ down.

To find the actual number of weeks Ramon must save, use division and round your number up to the closest natural number.

Answer:

Your estimate could be about $15$ weeks, but Ramon will actually need to save for $17$ weeks.
