Answer:
Percent of rise of a new truck on a used truck = 15%
Step-by-step explanation:
Let x be the percentage of saved money if Jason buying a used truck.
Given:
Price of the used truck = $34,000
Price of the new truck = $40,000
We need to find the percent of rise Jason saves on a used truck rather than buying a new truck
Solution:
Using a percentage formula.
[tex]percentage\ cost = \frac{(100-x)}{100}\times Original\ cost[/tex]
Substitute Percentage cost = 34,000 and Original cost = 40,000 in above formula.
[tex]34000 = \frac{(100-x)}{100}\times 40000[/tex]
[tex]34000 = (100-x)\times 400[/tex] ([tex]\frac{40000}{100}=400[/tex])
Using cross multiplication rule.
[tex](100-x)=\frac{34000}{400}[/tex]
[tex]85=100-x[/tex]
[tex]x = 100-85[/tex]
x = 15%
Therefore, Jason used 15% rise of a new truck for a used truck.
