Answer:
True
Step-by-step explanation:
The money was paid at an annual interest of 261.42%
Explanation:
- The initial amount of the guitar when it was loaned was $960. After a month the guitar cost $1,170. This means that in one month the price went from $960 to $1,170. Increase in cost = Difference between two costs = $1,170 - $960 = $210.
- To convert this into a percent we divide the difference in value by the original price and multiply the answer with 100 to convert it into a percentage. % increase in cost = difference between two costs / original cost % increase in cost = ($210 / $960) * 100 = 0.21785 * 100 = 21.785%
- This 21.875% was the monthly interest that was paid. To convert it into annual interest rate we multiply it with the 12 months.
- Annual interest rate = monthly interest rate * 12 = 21.785% * 12 = 261.42%. This means if the guitar was loaned for a year, you would have to pay $3469.44.
Answer:
The slope is -1/8 and the y intercept is 7/6
Step-by-step explanation:
This equation is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = -1/8 x + 7/6
The slope is -1/8 and the y intercept is 7/6
