Answer:
$32 is the sales price.
Step-by-step explanation:
First, change the percentage to a decimal.
60% = 60/100 = 0.6
Next, multiply 0.6 with the regular price ($80)
80 x 0.6 = 48
$48 is the discount. Subtract from the original price
80 - 48 = 32
$32 is the sales price.

Answer:
Given the statement:
8,000 earn in four years compounded daily at 5%
To find the amount we use formula:

where P is the principal , A is the amount , n is number of times compounded per year and t is the time in year.
Here, Principal(P) = $8000, r = 5% and n = 365
Substitute these given values we get;



Simplify:

To find the Interest we use formula:


It is also given that:
8,000 earn in four years compounded annually at 5%.
Here, P = $8000, r = 5% , t =4 year and n = 1
Using the same formula to calculate the amount:


Simplify:

To find the Interest :


Then;

Therefore, $47.23 more would $8,000 earn in four years compounded daily at 5% than compounded annually at 5%
Answer:
105:175
Step-by-step explanation:
3+5 = 8
3/8 of 280 is 105.
5/8 of 280 is 175.
the ratio is 105:175
next we have to simplify it:
divide both sides by 5:
21:35 divide both sides by 7=
3:5
Answer: 5^2
Step-by-step explanation:
Since the base are all the same, you will add the exponents and let the exponents stay the same.
5^3 * 5^4= 5^7 * 5^-5= 5^2
