A student has a savings account earning 9% simple interest. She must pay $1400 for first-semester tuition by September 1 and $14

00 for second-semester tuition by January 1. How much must she earn in the summer (by September 1) to pay the first-semester bill on time and still have the remainder of her summer earnings grow to $1400 between September 1 and January 1? (Round your answer to the nearest cent.)

Answer: The answer is $2,759.22

Explanation: From the question above, we have:

September 1st to January 1st is 4 months, this is 1/3 of a year which means that the student will earn:

=> 9/3 = 3%

3% interest for the money that is saved is the savings account. So the student must put in at least:

x + 3%x = 1400

x + 0.03x = 1400

1.03x = 1400

x = 1400 / 1.03

x = 1,359.22

Therefore, if the student saves $1,359.22 in the savings account By September 1st, she will have $1400 by January 1st.

Also, the student needs to make $1400 for the first semester. So overall she will need to make:

1,400 + 1,359.22 = $2,759.22 during the summer in order to ensure that she will have enough money to pay for both semesters.

If three sandwiches and two bags of chips cost $22. 00, and two sandwiches and one bag of chips cost $14. 25, how much does a ba
morpeh [17]

A bag of chips will cost $1.25. The price is calculated by making linear equations in two variables and solving them by substitution method.

<h3>What is a linear equation in two variables?</h3>

Linear equation in two variables can be defined as an equation in the form:

\rm ax + by = c , where x and y are variables and a and b are not equal to 0.

For the given problem, let "s" be the cost of a sandwich and "c" be the cost of a chips bag.

Given:

The cost of three sandwiches and two chips bags is $22.00.

Therefore, the 1st equation will be:

\rm 3s +2c = 22                              

The cost of two sandwiches and one chips bag is $14.25.

Therefore, the 2nd equation will be:

\rm 2s + c = 14.25

To calculate the cost of a chips bag, we need to solve equation 1 and equation 2 by the substitution method.

From equation 2, the value of c will be:

\begin{aligned}\rm 2s + c &= 14.25\\\\c &= 14.25 - 2s\end                                   ... (3)

Now we will put  \rm c = 14.25 - 2s  in equation 1:

\begin{aligned} \rm 3s + 2c &= 22\\\\3s + 2(14.25 - 2s) &= 22\\\\3s + 28.50 - 4s &= 22\\\\-s + 28.50 &= 22\\\\s &= 28.50 - 22\\\\s &= \$6.50\end

On substituting the value of s in equation 3:

\rm  c = 14.25 - 2s \\\\c = 14.25 - 2(6.50)\\\\c = 14.25 - 13\\\\c = \$1.25

Therefore the cost of a bag of chips is $1.25.

What is a trade-off?
mojhsa [17]
The best answer is:
C) <span>a choice that must be made due to scarcity.
A tradeoff occurs when you must choose between two or more things, selecting the best option given the constraints. Choosing what to spend your allowance on, for example, is involves a trade-off that you must make due to the scarcity of your allowance money (you don't have unlimited money). D is a tempting answer, but it does not define trade-off as well as C. </span>
