Step-by-step explanation:
Answer:
The rate charged by the first mechanic was $65 per hour and the rate charged by the second mechanic was $105 per hour
Step-by-step explanation:
Let
x ----> the amount charged per hour by the first mechanic
y ----> the amount charged per hour by the second mechanic
we know that
the sum of the two rates was $170 per hour
so
----> equation A
Together they charged a total of $1825
so
----> equation B
solve the system by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (65,105)
see the attached figure
therefore
The rate charged by the first mechanic was $65 per hour and the rate charged by the second mechanic was $105 per hour
