1 answer:
Musya8 [376]4 years ago
4 0

Answer:

16) 6%

17) 4 years

18) 2 years

Step-by-step explanation:

The formula for these questions is I = PRT

16) 27 = 900 (R) (0.5)

Notice how I used 0.5 instead of 6 for the T. T has to be measured in years, not months and 6 months is half a year.

R = 0.06 = 6 %

17) 480 = 2000 (0.06) (T)

T = 4 years

18) 1080 = 4500 (0.12) (T)

T = 2 years

1/2(10x +5) what is the value of the expression when x=1.4
Anon25 [30]

Answer:

19.2

Step-by-step explanation:

Rewrite 1/2(10x +5)  as  (1/2)(10x +5) for clarity.

Next, substitute 1.4 for x:

(1/2)(10[1.4] +5)

According to rules of operation, work inside parentheses must come before all else.  Thus we obtain:

(1/2)(14+5), or (1/2)(19).  Finally, this simplifies to 19/2.

A banker earns a $75,000 annual salary, a 2,35% commission on any approved loans for the bank’s business customers, and a fee of
satela [25.4K]

Answer:

Amount earned = $151,113

Step-by-step explanation:

Here, we are interested in calculating the banker’s earnings rounded to the nearest dollar;

We proceed as follows; we have the following;

1. Annual salary of $75,000

2. 2.35% on approved loans.

Approved loans = 2.8 million

Commission = 2.35/100 * 2.8 million = $65,800

3. $3.75 for each processed loan application

Total = 2750

Amount = 3.75 * 2750 = $10,312.50

Total amount earned is thus;

$75,000 + $65,800 + $10,312.50 = 151,112.5 = 151,113 to the nearest dollar

Karyn proofreads 15 pages in 2 hours for $40. What is her proofreading rate in pages per hour?
vladimir1956 [14]
Hey there,
2 hours = 15 pages
1 hour = 15 / 2
           = 7.5 pages
15 pages = $40
1 page = $40 / 15
            = $2.666666666666667
7.5 pages= $2.666666666666667 x 7.5
               = $20

Hope this helps :))
