Question

The relationship between the number of months and cumulative cell phone cost is represented by the scatter plot shown.Cumulative Cost500500+400-Cumulative Cell Phone Cost (dollars)(10, 504)(9.470)(8.418)•7, 361)(6.324).5253)13.151.14. 196)300100101.55 2. 108)Number of MonthsA line of best fit for this data is C = 51 + 4.4, where is the cumulative cell phone cost and m is the number of months.Using this data which value is the best prediction of the cumulative cell phone cost after 18 months?AS91885923Oc5940OD 5990

Answer 1

For this problem we have the following function given:

`C=51+4.4m`

tnaw eWhere C represent the cumulative cost and m the number of months. We want to estimate the cumulative cost after m=18 months so we just need to replace in the function and we got:
