A handy man charges $25 per hour, plus a $40 service fee. Write an equation to represent this situation, and then determine the cost of a 3 hour service call

Step-by-step explanation:

Straightline equation problem

given data

charges per hour= $25

service fee= $40

time =3 hours

the equation can be represented using the equation of line

y=mx+c

y= the total charges

x= the number of hours

c= the service fee

m= the charge per hour

y=25x+401

for x=3

y=25(3)+40

y=75+40

y=115

the total is $115

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of
