Respuesta :

Explanation:

Jeweler A: y=15x+125       (y=15(1)+125)

Jeweler B: y=12x+140        (y=12(1)+140)

        Graph:

A                 - x -               B

140                1                  152

155                2                 164

170                3                 176

185                4                 188

200               5                 200

 Answer:              

The two jewelers meet at the 5th hour.

Based on the amount charged by both jewelers, the total cost of using either will be the same after 5 hours.

The jeweler is charging $125 initially and then $15 per hour. In equation form, and assuming the number of hours is x, this is:

= Initial cost + (Amount per hour x Number of hours)

= 125 + (15 × x)

= 125 + 15x

The second jeweler is:

= 140 + 12x

To find the number of hours they will be equal, equate both formulas:

125 + 15x = 140 + 12x

15x - 12x = 140 - 125

3x = 15

x = 15/3

x = 5 hours

In conclusion, they will charge the same after 5 hours.
