Using the condition given to build an inequality, it is found that the maximum number of junior high school student he can still recruit is of 17.

<h3>Inequality:</h3>

Considering s the number of senior students and j the number of junior students, and that he cannot recruit more than 50 people, the inequality that models the number of students he can still recruit is:

s + j \leq 50

In this problem:

  • Already recruited 28 senior high students, hence s = 28.
  • Already recruited 5 junior high students, want to recruit more, hence j = j + 5.

Then:

28 + j + 5 \leq 50

33 + j \leq 50

j \leq 17

The maximum number of junior high school student he can still recruit is of 17.

Question 10
antoniya [11.8K]

Answer:

$11,500 was invested at 13%.

$17,500 was invested at 4%

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

T = E + P

In this question:

Loans totaling 29,000.

P was invested at 13%

29000 - P was invested at 4%.

First investment:

Principal P.

Interest 13% = 0.13.

One year, so t = 1.

So

E_{1} = P*0.13*1

E_{1} = 0.13P

Second investment:

Principal 29000 - P.

Interest 4% = 0.04.

One year, so t = 1.

So

E_{2} = (29000-P)*0.04

The total interest earned for both loans was $2,195.00.

This means that E_{1} + E_{2} = 2195

So

E_{2} = 2195 - E_{1}

So we solve the following system:

E_{1} = 0.13P

E_{2} = (29000-P)*0.04

2195 - E_{1} = (29000-P)*0.04

2195 - 0.13P = 1160 - 0.04P

0.09P = 2195 - 1160

P = \frac{2195 - 1160}{0.09}

P = 11500

$11,500 was invested at 13%.

29000 - 11500 = 17500

$17,500 was invested at 4%
