Answer:
Ronnie spent 5 hours working.
Step-by-step explanation:
From the information given, the total cost of the job is equal to the flat fee plus the result of multiplying the cost per hour for the number of hours which is:
c=25+30x, where:
c is the total cost of the job
x is the number of hours
Now, you can replace c with 175 and solve for x:
175=25+30x
175-25=30x
150=30x
x=150/30
x=5
According to this, the answer is that Ronnie spent 5 hours working.
You know 36 is 90% of a value, so it will equal 90/100.
Multiply 90/100 types x (value). Easiest way is to simplify 90/100 = 9/10.
x = 36 / 9/10
x = 360 / 9
x = 40
Therefore, the value would be 40.
