The difference of the quotient m and 9 and the quotient of n and 30

1 answer:

5 0

Answer: (30m-9n)/270

First we start with m/9-n/30.

We multiply the denominators to get 270.

Then we multiply the numerators by the original denominators to get (30m-9n).

To check, we can use m=2, and n=4

2/9-4/30=4/45

(30*2-9*4)/270=24/270=4/45

You are a running a concession stand selling hot dogs and sodas each hot dog costs .75 cents and each soda costs $1.25. You sold

tatiyna

Each hot dog costs $ 1.50 and each soda costs $ .50. You made a total of $ 78.50. You sold a total of 87 hot dogs and sodas combined. You must report the number of hot dogs and soda's sold. How many hot dogs and soda's were sold?

Quantity Equation: h + s = 87
Value Equation:: 1.5h+0.5s=78.50

Multiply thru the Quantity Equation by 15
Multiply thru the Value Equation by 10.

15h + 15s = 15*87
15h + 5s = 785Subtract and solve for "s":10s = 520
s = 52 (# of soda's sold)

Solve for h:
h + s = 87
h + 52 = 87
h = 35 (# of hot dog's sold)

nata0808 [166]

Answer:

$8146.67

Step-by-step explanation:

Under the U.S. Rule, unpaid accrued interest is accumulated separately and is not added to principal. In addition, interest is not calculated until a payment is made.

Principal = $12 000.00

1st period = 40 days

Interest on 1st period

= $12 000 × 0.11 × 40/360 Interest = 146.67

Principal + interest = 12 146.67

-Partial payment = 4 000.00

Adjusted balance = $ 8 146.67

Roger's adjusted balance after the first payment is $8146.67.
