Traci and Ben want to compare the points scored in the last fifteen games by their favorite basketball teams. To compare the variability in the scores should they use the range, interquartile range or mean absolute deviation of the scores? Explain your choice.​

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).
