Ответ:
The answer is Y = 14.
Ответ:
a. $37.5
b. $40
c. $42.5
Step-by-step explanation:
We know the monthly $35 is the same for all three, since it's all one month.
What's different is the amount of money spent. 10 minutes would cost $0.25*10 = $2.5
20 minutes would cost $5
and 30 minutes would cost $7.5
add these costs to $35.
