Alina [70]

$390 is the interest will Charlie’s initial investment earn over the 15-year period. The money does Charlie have after the 15 years is $715.

<u>Step-by-step explanation:</u>

Harlie invests $325 in an account.

  • Principal, P = $325
  • Interest rate, r = 8% ⇒ 0.08
  • Number of years, t = 15

<u>The formula to find the interest will Charlie’s initial investment earn over the 15-year period :</u>

⇒ I = Prt<u></u>

⇒ 325\times 0.08\times15

⇒ 390

Therefore, $390 is the interest will Charlie’s initial investment earn over the 15-year period.

<u>Money Charlie has after 15 years :</u>

It is given by the formula,

⇒ Amount = Principal + Interest.

⇒ 325 + 390

⇒ 715 dollars.

∴ The money does Charlie have after the 15 years is $715.

nekit [7.7K]

Answer:

160

Step-by-step explanation:

In math, the word of means multiply. :)

3/8 * 640 = 240, so there are 240 1p coins.

there are the same number of 5P coins, so there are 240 5p.

640 - 1p - 5p = 2p

640-240-240 = 160, so there are 160 2p coins.

Tanya took a cab from her home to the airport. Her total fare including a tip of $5.00, was $28.50. EZ Cab Company has a pick-up
ValentinkaMS [17]
16.2 miles.

Since she paid a $5 tip, the cost for her fare was $23.50.  Let x be the number of 0.2-mile increments in the trip:
23.50 = 2.50 + 1 + 0.25(x-1)

This equation comes from the 2.50 home pick-up fee; $1 for the first 0.2-mile increment; and 0.25 for each other 0.2-mile increment.

Using the distributive property, we have:
23.50 = 2.50 + 1 + 0.25*x - 0.25*1
23.50 = 2.50 + 1 + 0.25x - 0.25

Combining like terms,
23.50 = 0.25x + 2.75

Subtracting 2.75 from both sides, we have:
23.50 - 2.75 = 0.25x + 2.75 - 2.75
20.25 = 0.25x

Dividing both sides by 0.25, we have:
20.25/0.25 = 0.25x/0.25
81 = x

This means there are 81 0.2-mile increments in her trip.  81(0.2) = 16.2 miles
