Answer:

6.6%

Step-by-step explanation:

Note: I had to correct the given data

Given data

Initial charges= $7.50

Final charges= $8.0

Percent increase

% increase= Final-initial/initia*100

% increase= 8-7.5/7.5*100

% increase= 0.5/7.5*100

% increase= 0.066*100

% increase= 6.6%

A small telescope magnifies
WARRIOR [948]

The observatory telescope has 22 times the magnifying power compared to the small telescope.

Data;

  • small telescope = 150 times
  • large telescope = 3300

<h3>Division of Numbers</h3>

To solve this question, we have to divide the large telescope by the small telescope to calculate it's magnifying power.

x = \frac{3300}{150}=22

The magnification of the observatory telescope is 22 times greater or larger than the small telescope.

HELP you purchase a car using a $22,000 loan with a 6% simple interest rate for 5 years
Hunter-Best [27]

Answer:  (a) $6,600

                (b) $28,600

<u>Step-by-step explanation:</u>

Interest (I) = Principal (P) x rate (r) x time (t)

I = 22,000(0.06)(5)

 = 6,600


Accrued (A) = Principal (P) + Interest (I)

A = 22,000 + 6,600

  = 28,600
