Katarina [22]

Answer:

The number of knitted scarves is 10

The number of knitted mitten is 20

Step-by-step explanation:

Given as :

The cost of each knitted scarves = $50

The cost of pairs of mittens = $25

Total number of scarves and mitten bought = 30

The total money invested to pay for items = $1000

Let The number of knitted scarves = k

Let The number of mitten = m

<u>Now, According to question</u>

The total money invested to pay for items = cost of each knitted scarves × number of knitted scarves + cost of pairs of mittens × number of mitten

i.e $1000 = $50 × k + $25 × m

Or, 40 = 2 k + m

i.e 2 k + m = 40 ........A

And

Total number of scarves and mitten bought = number of knitted scarves + number of mitten

i.e k + m = 30 ...........B

Now, solving eq A and eq B

So, (2 k + m ) - ( k + m ) = 40 - 30

Or, (2 k - k) + ( m - m) = 10

Or, k + 0 = 10

∴ k = 10

So, The number of knitted scarves = k = 10

Put the value of k into eq B

∵ k + m = 30

So, m = 30 - k

or, m = 30 - 10

∴ m = 20

The number of knitted mitten = m = 20

Hence, The number of knitted scarves is 10 and The number of knitted mitten is 20 . Answer

Question is Incomplete; Complete question is given below;

Mr. Lin hires a moving company to help transport furniture to his new home. The bill from the moving company is $400. Mr. Lin includes a 15% tip with his payment.

What is Mr. Lin’s total payment, including tip?

Answer:

Mr. Lin made a Total payment of $460 including the Tip.

Step-by-step explanation:

Given:

Total bill = $400

Percentile amount paid in tip = 15%

We need to find the total payment, including tip.

Solution:

First we will find the amount paid in Tip.

amount paid in Tip can be calculated by Percentile amount paid in tip multiplied by Total bill and then divided 100.

amount paid in Tip = $\frac{15}{100}\times 400 = \$60$

Now we know that;

Total payment made by Mr.Lin is equal to sum of Total bill and amount paid in Tip.

framing in equation form we get;

Total payment made by Mr.Lin = $\$400+\$60 =\$460$

Hence Mr. Lin made a Total payment of $460 including the Tip.
