The costs of the plans will have the form:
$$ \large \rm base~ price + price ~per~ text \times \# texts$$ So for instance the first plan will be $$ \large 60 + 0.05 \times t $$

Answer 26

you will have to redo these
1.
plan A : (60 + 0.05*t ) ( 1.06)
plan B : (80 + 0.02*t) ( 1.06)
plan C : (99+0.05*t) ( 1.06)
plan D : (75 + 0.07*t) ( 1.06 )

2.
plan A : (60 + 0.05*500 ) (1.06 )= $90.10
plan B : (80 + 0.02*500) (1.06 )= $95.40
plan C : (99+0.05*500) ( 1.06 ) = $116.60
plan D : (75 + 0.07*500) ( 1.06 ) = $131.44

Answer 27

multiplying by 1.06 accounts for the tax

Answer 28

so the answer for 2 would still have been A

Now we need to recalculate for part 3, since you used 5GB of data, do you have an idea on how to reorganize this?
