Question

3 diego and efia are looking at cell phone plans. they could share a group plan that costs $119.95 per month, or they could each pay for an individual plan that costs $62.77 per month. a. estimate which choice would cost less for diego and efia. explain why. b. how much money could they save per month by paying for the choice that costs less instead of the choice that costs more? show your work.

Explanation:

Part a

To estimate, round the individual plan cost (\$62.77) to \$63. For two people, the total for individual plans is approximately \( 63\times2 = 126 \). The group plan is \$119.95, which is about \$120. Since \$120 < \$126, the group plan should cost less.

Step1: Calculate total for individual plans

Each individual plan is \$62.77, so for two people, total is \( 62.77\times2 \).
\( 62.77\times2 = 125.54 \)

Step2: Find the difference between individual total and group plan

Subtract the group plan cost (\$119.95) from the individual total (\$125.54).
\( 125.54 - 119.95 = 5.59 \)

Answer:

The group plan (costing \$119.95 per month) would cost less. Estimating the total for two individual plans (rounding \$62.77 to \$63) gives LXI0, and \$119.95 (group plan) is less than \$126.
