Two mechanics work on a car . The first mechanic worked 10 hours and the second mechanic worked for 15 hours. Together they charged a total of $2050. What was the rate charged by each mechanic if the sum of the two rates was $16 per hour?

and

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 $16 per hour

so

----> equation A

Together they charged a total of $2050

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 (124,54)

see the attached figure

Find the rate charged by each mechanic

yes yes yes

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
