Aclub had some money to purchase new chairs after buying 355chairs at 199$ there was 1068$ remaining how much money did the club had first

The amount of money the club had first is $71,713

To determine how much money the club has first, we can derive solution to it by using the area model method. (Please refer to the attachment below)

What we should do first is to calculate the total amount of money spend on chairs by multiplying the chair purchased and the price per each chair

Therefore, we have:

355 x 199

= (300 + 50 + 5) x (100 + 90 + 9)

= (300 x 100) + (300 x 90) + (300 x 9) + (50 x 100) + (50 x 90) + (50 + 9) (5 x 100) + (5 x 90) + (5 x 9)

= 30000 + 27000 + 2700 + 5000 + 4500 + 450 + 500 + 450 + 45

= 70645

Therefore, the total money spend on chairs is 70,645

Recall, we have to calculate the money the club has first before purchase, then we can derive this by adding the total money spend on chairs and the money the club has after purchase.

Therefore we have:

= 70645 + 1068

= 71,713

Therefore, the money the club has at first before purchasing new chairs is 71,713.

You can also solve this quickly by multiplying the chair purchased by the club and the price per each chair, then the value derived should be added to the money the club has after purchase.

Hence,

= 355 x 199

= 70645

= 70645 + 1068

= 71,713.

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
