Cathy lives in a state where speeders fined $ 10 for each mile per hour over the s speed limit cathy was given a fine for $80for speeding on a road where the speed limit is 50 miles per hour how fast was cathy driving

58 miles per hour

Step-by-step explanation:

First you need to divide 80 by 10 to see how many miles she was over the speed limit.

80/10 = 8 miles over the speed limit.

The speed limit was 50, so 50 + 8 = 58 miles.

So Cathy was driving at 58 miles per hour

58mph

Step-by-step explanation:

Given:

Each mph over the speed limit gets fined $10

or mathematically, rate of fine = $10/mph

also, total fine was $80.

Number of mph over the speed limit,

= total fine ÷ rate of fine

= $80 ÷ $10/mph

= 8 mph.

Given that the speed limit was 50 mph, Cathy's final speed,

= speed limit + number of mph over speed limit

= 50 + 8

= 58 mph

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)
