9514 1404 393

Answer:

  54

Step-by-step explanation:

Let d represent the number of donuts. The cost is proportional to the number, so we have ...

  d/33.00 = 9/5.50

  d = 33.00(9/5.5) = 9·6 = 54

You can buy 54 donuts for $33.00.

There are 240 coins in a jar, all dimes and quarters. The value of the coins in the jar is $27.60. There are nine times as many
SashulF [63]
I believe it is 28 dimes
.25 × 30 = 7.50
.10 × 190 = 19
19 + 7.50 = 26.50
Then, you add 4 more quarters which is 27.50 and the 28 dime makes it 27.60

Solnce55 [7]

In this question they've given us the formula and they just want us to plug in the numbers and get the value.


P is the original value, P=$600


r is the depreciation rate, r=10%=0.1


t is the time in years, t=2


A = P(1-r)^t = 600(1 - 0.1)^2 = 600 \cdot .9^2 = 486


Answer: $486
