sweet [91]

Answer:

1 point baskets = 19

2 point baskets = 22

3 point baskets = 5

Step-by-step explanation:

Given:

Number of points scored (P) = 78

Number of 1 point baskets = 19

Number of 2 and 3 points basket = 27

Let the number of 2 point baskets be 'x' and 3 point basket be 'y'.

Therefore,

$x+ y=27\\\\y=27-x$

Now, points scored per 2 point basket = 2

So, points scored for 'x' baskets = $2x$

Also, points scored for 'y' baskets = $3y=3(27-x)=81-3x$

Now, total points scored is equal to the sum of 1 point baskets, 2 point baskets and 3 point baskets. Therefore,

$P=19+2x+81-3x\\\\78=100-x\\\\x=100-78\\\\x=22$

Therefore, number of 2 point baskets = 22

Now, number of 3 point baskets = 27 - 22 = 5

So, there were 19 one point baskets, 22 two point baskets and 5 three point baskets.

<span>c. This budget can be modified by reducing the amount spent on food and clothes, thereby reducing overall expenses to have the maximum amount of money for fixed expenses and maintaining a positive actual net income.

You can't reduce fixed expenses. These are expenses that are constant every month like rent expense, utility payments, and cell phone plan. The only expenses you can reduce are food and clothes. These expenses are called variable expenses meaning the amount of these expenses varies. Thus, it can be manipulated. </span>
