- You need to write the following three equations, where $a$ is the the number of apples, $p$ is the number of pears and $o$ is the number of oranges:

1) $a+p=184$

2) $a+o=248$

3) $o=3p$

- You must substitute the equation 3) into the equation 2):

$a+3p=248$

- Now, you need to solve for $p$ in the equation 1) and then you must substitute it into $a+3p=248$ :

$p=184-a$

$a+3(184-a)=248$

- Solve for $a$ , as following:

$a+552-3a=248\\-2a=-304\\a=\frac{-304}{-2}\\a=152$

- Therefore, there are 152 apples.

Megan has $50 and saves $5.50 each week. Conner has $18.50 and saves $7.75 each week. After how many weeks will Megan and conner

QveST [7]

After 14 weeks, both Megan and Conner will have saved the same amount.

Step-by-step explanation:

Amount Megan have = $50

Amount saved each week = $5.50

Amount Conner have = $18.50

Amount saved each week = $7.75

Let,

x be the number of weeks.

According to given statement;

M(x) = 50+5.50x Eqn 1

C(x) = 18.50+7.75x Eqn 2

For amount to be same;

Eqn 1 = Eqn 2

$50+5.50x=18.50+7.75x\\50-18.50=7.75x-5.50x\\31.50=2.25x\\2.25x=31.50\\$

Dividing both sides by 2.25

$\frac{2.25x}{2.25}=\frac{31.50}{2.25}\\x=14$

After 14 weeks, both Megan and Conner will have saved the same amount.
