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.
