Answer:
mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other.
8 - direct variation Since the equation can be written in the form y=kx. , y varies directly with x and k. The constant of variation, k, is 3.25
9 - When solving for y, y=5x-9 so y doesn't vary directly with x.
y doesn't vary directly with x
10 - direct variation Since the equation can be written in the form y=kx, y varies directly with x and k. The constant of variation, k, is -2.4
Answer:
Finance charge = $1500
Step-by-step explanation:
Cost price of jukebox = $9400
Down payment made by a local diner = $1000
Balance amount to be paid = 9400 - 1000 = $8400
In order to pay the balance amount diner agreed upon the installments = $275 per month for 36 months
Total amount to be paid in 36 months = 275 × 36 = $9900
So extra payment done = Total balance amount - Amount paid in 36 installments
= 9900 - 8400
= $1500
Therefore, finance charge paid by the diner was $1500.
