Answer: A, D, & E
Step-by-step explanation:
they are all correct when 5 is plugged in.
<span>We can determine, a 30/25/15 series trade discount would be calculated as follows:
let X = retail price.
X - 0.30 </span>× X = Y ⇒ first discounted price.
<span>
Y - 0.25 </span>× Y = Z ⇒ second discounted price.
<span>
Z - 0.15*Z = T </span>⇒ total discounted price.
<span>
X - 0.30 </span>× X = (1 - 0.30) × X = 0.70 × X = Y
<span>
Y - 0.25 </span>× Y = (1 - 0.25) × Y = 0.75 × Y = Z
<span>
Z - 0.15 </span>× Z = (1 - 0.15) × Z = 0.85 × Z = T
<span>
since Z = 0.85 </span>× Y, then 0.85 × Z = 0.85 × 0.75 × Y
<span>
since Y = 0.70 </span>× X, then 0.85 × Z = 0.85 × 0.75 × 0.70 × X
<span>
based on the above, then T = total discount
= 0.85 </span>× 0.75 × 0.70 × X
= 0.44625X<span>
30/25/15 series discount is equivalent to a total discount of 44.625%

Answer:
Step-by-step explanation:
Since it is simple interest, you have to use the formula I = Prt.
(I is interest, P is principal (the starting amount), and r is the & rate as a decimal.
So, the interest would be
I = 543,300 (0.048) (2) = $52,156.80
The balance is the total amount. The balance would be the starting amount plus the interest.
Balance = 543,300 + 52,156.80 = $595,456.80
