Respuesta :

Answer:

5 months

i added 8 to 28 till i got a # that 12 is divisible by

Answer:

After 7 months will both packages cost the same.

Step-by-step explanation:

Let the month after which both the packages will cost the same be x.

Cost of data package-1 for x months = $28+$8x

Cost of data package-2 for x months =$12x

Cost of data package-1 for x months = Cost of data package-2 for x months

[tex]\$28+\$8x=\$12x[/tex]

[tex]\$28=\$12x-\$8x[/tex]

[tex]x=\frac{28}{4}=7[/tex]

After 7 months will both packages cost the same.
