Question

Will medal and fan please help!!!
Noelle needs to have her computer fixed. One company charges a 25$ estimation fee plus 45$ per hour. Another company charges a 10$ estimation fee plus $60 per hour, Find the number of hours for which the two costs would be the same.

Answer 1

We have two known numbers without any further need of changing (estimation fee) and the time fee. So, the costs are, as formula:

for company A \[25+45x =y\]
for company B \[10+60x=y\]

x is the hours and y is the final cost when they are equal. Does that help you at all? @Twix47

Answer 2

yeah thanks

Answer 3

So, the easiest is to set them as equal to each other:

\[25+45x=10+60x\] Now simplify and solve for x.
