Explanation:

Step1: Calculate cost for A - Mobile

First two lines cost $19$.
Number of additional lines: $4 - 2=2$.
Cost for additional lines: $2\times7 = 14$.
Total cost for A - Mobile: $19+14=\$33$.

Step2: Calculate cost for B - Mobile

First two lines cost $15$.
Number of additional lines: $4 - 2 = 2$.
Cost for additional lines: $2\times8=16$.
Total cost for B - Mobile: $15 + 16=\$31$.

Step3: Compare costs and find savings

Since $31<33$, choose B - Mobile.
Savings: $33-31=\$2$.

Answer:

Which family plan should Ethan’s family go with? B - Mobile.
How much will the family save by doing that? $\$2$.
