Answer:
Step-by-step explanation:
Given
Call out fee = £35
Per hour = £30
Time = 2 hours
Per light switch = 12 minutes
Required
Cost of wiring a house with 10 light switches
First, the minutes on the 10 light switches should be calculated'
If time per light switch is 12 minutes;
then
Time for 10 = 12 minutes * 10
Time for 10 = 120 minutes
[Convert to hours]
Time for 10 = 2 hours
Next is to calculate the total time spent altogether
Time = 2 hours + Time spent on 10 light switches
Time = 2 hours + Additional 2 hours
Time = 4 hours
Total Charges = Call out fee + Charges per hour * Time
Total Charges = £35 + £30 * 4
Total Charges = £35 + £120
Total Charges = £155
Answer: p = 1/5
Step-by-step explanation:
-5(p + 3/5) = -4
Distribute
-5p - 3 = -4
Add 3 to both sides
-5p = -1
Divide by -5 on both sides
p = 1/5
Answer:
Step-by-step explanation:
The amount that Rita and Tina each make per hour working as cashiers at a supermarket is $11.
Last week, Rita worked r hours. It means that the amount that Rita made last week, working for r regular hours is 11r. Rita also worked overtime hours during the week, for which she was paid an extra $32 flat wage. It means that the total amount earned by Rita last week was
11r + 32
Last week, Tina worked for t hours. It means that the amount earned by Tina last week was 11t
The expression representing the total weekly wages of both Rita and Tina is
11r + 32 + 11t
2x+19 = x+23
x=4
So the answer is C
