Answer:

<u><em>Christopher is 24 years old.</em></u>

Step-by-step explanation:

<u>c = Christopher's age</u>

<u>i = Ishaan</u>

c = i - 20

(i- 14) = 3(c - 14)

<em>simplify</em>

i - 14 = 3c - 42

i - 14 = 3(i - 20) - 42

i - 14 = 3i - 60 - 42

i - 14 = 3i - 102

<em>take i to the other side</em>

- 14 = 2i - 102

<em>take - 102 to the other side</em>

88 = 2i

44 = i

<u>Ishaan is 44 years old.</u>

<em>The question said to find Christopher's age. So:</em>

c = i - 20

c = 44 - 20

c = 24

<u><em>Christopher is 24 years old.</em></u>

Dustin has only nickels and quarters in his piggy bank. He has 49 coins total for a combination value of $8.85. How many of each
stepan [7]

Answer: he has 32 quarters and 17 nickels.

Step-by-step explanation:

The worth of a quarter is 25 cents. Converting to dollars, it becomes

25/100 = $0.25

The worth of a nickel is 5 cents. Converting to dollars, it becomes

5/100 = $0.05

Let x represent the number of quarters that he has in her wallet.

Let y represent the number of nickels that she has in her wallet.

He has 49 coins total. This means that

x + y = 49

the total value of the coins is $8.85. This means that

0.25x + 0.05y = 8.85 - - - - - - - - - - 1

Substituting x = 49 - y into equation 1, it becomes

0.25(49 - y) + 0.05y = 8.85

12.25 - 0.25y + 0.05y = 8.85

- 0.25y + 0.05y = 8.85 - 12.25

0.2y = 3.4

y = 3.4/0.2

y = 17

x = 49 - y = 49 - 17

x = 32

20.70=3p+3
17.70=3p
$5.90=p
So if you only needed the equation to describe the word problem it is
$20.70=3p+3

If you want to know how much each pizza was it is $5.90; salad $3.00
