Answer:

m= masters degree salary and b=bachelors degree salary.

m = 2b - 45000

m + b = 112000

Substitute to get

2b - 45000 + b = 112000

3b = 156000

b = 52000

So m = 59000

Check to see if these numbers work

59000 = 2*52000 - 45000 true

59000 + 52000 = 112000 true

what was the original principal for an 8% simple interest bank account that holds $4340 after 3 years?
Solnce55 [7]

Answer:

The original deposited amount in the bank is $3500.

Step-by-step explanation:

Here. Let us assume the principal amount deposited in bank =  $P

The rate of interest = 8%

Total Amount in the bank after time period  =  $4340

Time Period = 3 yrs

Now, SIMPLE INTEREST = \frac{P \times R \times T}{100}

⇒ SI = SI = \frac{P \times 8 \times 3}{100} = 0.24P

or Interest =  0.24 P

Now, AMOUNT  = PRINCIPAL + INTEREST

⇒$4340  = P +  0.24 P

or, 4340 = 1.24 P

⇒ P = 1340 / 1.24 = 3500

Hence, the deposited amount in the bank for the duration of 3 years and interest rate 8%  is $3500

14.4 A Book and a Cake A book costs $45. Sales tax on the book is 7%. Write two different expressions that represent the final c
snow_tiger [21]

Answer: 1. $45*1.07 | $45(1.07) 2. (0.85)*32 represent the final price of the cake in dollars because (0.85) is the 15% off in decimals.

Step-by-step explanation:

1 if you multiply 45 by 1.07 it will be 48.15 and that's the final cost of the book, same with $45(1.07) is just another way to represent the multiplication.

2 As I said the 0.85 represent the 15% off, and when you multiply it will be less.
