Complete question :
Dusty won $125,000 on the Who Wants to be a Zillionaire? game show. He decides to place the money into an account that earns 6.25% interest compounded annually and plans not to use any of it until he retires. a. Write an equation that represents the amount of money Dusty will have in n years. b. How much money will be in the account when he retires in 23 years?
Answer:
A = 125000(1.0625)^n ;
$504052.30
Step-by-step explanation:
Going by the compound interest formula :
A = P(1 + r/n)^nt
Here, P = amount won ; A = final amount ; r = interest rate = 6.25% = 0.0625 ; n = 1 ; t = number of years
Hence, the amojt of money, A Dusty will. Have in n years ;
A = 125000(1 + 0.0625)^n
A = 125000(1.0625)^n
Amount he'll have in 23 years
n = 23
A = 125000(1.0625)^23
A = 125000 * 4.03241
A = $504052.30
<h3>
Answer: 0.85</h3>
Explanation:
If we start off with $100 and decrease by 15%, then we are decreasing by $15 since 15% of 100 = 0.15*100 = 15
We start with $100 and drop to 100-15 = 85. Dividing this over the original 100 gets us 85/100 = 0.85
Put another way, 100% - 15% = 1 - 0.15 = 0.85
The decimal multiplier for "decrease by 15%" is 0.85; this sort of thing is useful if you wish to apply multiple discounts to a product.
Side note: the 0.85 can be thought of as 85%, so the product's new value is 85% of its original value
Equation would be y=x+5/8
Answer:
Step-by-step explanation:
y-intercept is -4
69 - 3a = 0
69 - 3a (-69) = 0 (-69)
-3a = -69
-3a(/-3) = -69(/-3)
a = 23
