Amount of money in the hand of Wade = $175
Cost of each sweater = $12
Amount of money that needs to be in the hand of Wade after buying sweater = $55
Let us assume the number of sweaters that Wade can buy = x
Then
12x + 55 = 175
This is the inequality equation that has to be solved to find the number of sweaters that Wade can buy.
So
12x + 55 = 175
12x = 175 -55
12x = 120
x = 120/12
  = 10
So Wade can buy a total of 10 sweaters and still have $55 in his hand. I hope the procedure of doing this problem is clear to you.

Using the monthly payment formula, it is found that her down payment should be of $1,419.

<h3>What is the monthly payment formula?</h3>

It is given by:

A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}

In which:

  • P is the initial amount.
  • r is the interest rate.
  • n is the number of payments.

For this problem, the parameters are:

A = 250, r = 0.072, n = 72.

Hence:

r/12 = 0.072/12 = 0.006.

We solve for P to find the total amount of the monthly payments, hence:

A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}

P\frac{0.006(1.006)^{72}}{(1.006)^{72}-1} = 250

0.0171452057P = 250

P = 250/0.0171452057

P = $14,581.

The total payment is of $16,000, hence her down payment should be of:

16000 - 14581 = $1,419.

You need to divide 9 to both sides in order for y to come alone. So then you would have to divide 27 by 9 and y = 3. Hope this helps!

A farmer sells 8.3 kg of apples and pears at the farmers market this way is apples and Restless Paris how many kilograms of Pari
Serga [27]

Answer:

She sell <u>2.075 kilograms</u> of pears at the farmer's market.

Step-by-step explanation:

<u><em>There is a mistake in the question some data is missing, so the correct question is below: </em></u>

<em>A farmer sells 8.3 kg of apples and pears at the farmer's market. 3 /4 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market?</em>

Now, to find the kilograms of pears.

Total weight of apples and pears = 8.3 kg.

Weight of apples = \frac{3}{4} of 8.3 kg.

So, to get the weight of apples:

  \frac{3}{4} \times 8.3

=0.75\times 8.3

=6.225\ kg.

Thus, the weight of apples = 6.225 kg.

Now, to get the weight of pears we subtract the weight of apples from the total weight of apples and pears:

8.3-6.225\\\\=2.075\ kg.

Therefore, she sell 2.075 kilograms of pears at the farmer's market.
