Answer:
$111
Step-by-step explanation:
First we need to take a look at the bank account of Hakim. Hakim initially invested $700 in the bank with a 5% simple interest annually. Since Hakim waited for an entire year before buying the computer, he will then have the extra 5% interest from the bank.
Let's first compute for how much Hakim will have in total in the bank.
A = P(1 + rt)
P = 700 Initial Investment
r = 5% or 0.05 Interest
t = 1 Year
A = 700(1 + (0.05 x 1))
A = 700(1 + 0.05)
A = 700(1.05)
A = 735
So now we know that Hakim has a total of $735 in his bank account.
Now let's move on to calculating the total cost of the computer. We know that the sales tax is always computed after the discounted price.
So first we find the discounted price.
x = 750
d = 20% or 0.20
Discount = 750 x 0.20
Discount = 150
Now that we have the discount of the computer, we then simply subtract the discount to the initial price.
750 - 150 = 600.
The computer will then cost $600 with the discounted price.
Now we have to find the sales tax.
Sales Tax = 4% or 0.04
Total Discounted Price = 600
600 x 0.04 = $24
Now that we have the sales tax, we simply add the sales tax to the discounted price.
600 + 24 = 624.
Now that we know how much the total cost of the computer is with the discount and sales tax, we simply subtract the total cost of the computer to Hakim's current account balance.
735 - 624 = 111
Hakim will have a total of $111 in his bank account after purchasing the computer.
Answer:
There are 144 faculty at the college are certified
Step-by-step explanation:
- A local community college employs 240 full time faculty
∴ There are 240 full time employs
- Approximately 3/5 of the full time faculty are certified to teach online
∴ 3/5 of the total 240 are certified to teach on line
- We need to find how many faculty at the college are certified
<em>To find that multiply the fraction of the certified by the total number </em>
<em>of the full time faculty</em>
∵ The fraction of certified is 3/5
∵ The total of the full time faculty is 240
∴ The number of certified = 
× 240
∴ The number of certified = 144
<em>There are 144 faculty at the college are certified</em>
