Kayla went over the allotted cell phone minutes this month by 42 minutes. her regular bill is $39.95, but this month is was $54.65. which ratio compares her overtime minutes to the cost of those minutes?

The ratio of overtime minutes to the cost of those minutes is 42 : 14.7

Solution:

Kayla went over the allotted cell phone minutes this month by 42 minutes

Therefore,

over time minutes = 42 minutes

Her regular bill is $39.95, but this month is was $54.65

Regular bill = $ 39.95

This month bill = $ 54.65

Therefore, cost for overtime minute is given by:

cost for overtime minute = This month bill - regular bill

cost for overtime minute = $ 54.65 - $ 39.95

cost for overtime minute = 14.7

Thus ratio of over time minutes to cost of those minutes is given by:

Thus the required ratio is found

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
