£1400

A reduction of 40% means that £840 is 60% of the original price

Divide £840 by 60 to find 1% then multiply by 100 to find original price

original price = £840 × \frac{100}{60} = £1400

Answer:

$1400

Step-by-step explanation:

Given: A ring cost $840 after a discount of 40% on the original price of the ring.

To find: Original price of the ring

Solution:

Let the original price of the ring be $x

It is given that a discount of 40% on the original price of the ring. So, we have

    x-\frac{40}{100}\times x=840

\implies x-\frac{2x}{5} =840

\implies\frac{5x-2x}{5} =840

\implies\frac{3x}{5} =840

\implies x=\frac{840\times5}{3}

\implies x=280\times5

\implies x=1400

Hence, the original price of the ring is $1400.

A minor-league hockey team had the following scores for the start of the season: 3, 6, 2, 1, 2, 3, 0, 4, 5, 1, 5, 4.
ale4655 [162]

If the hockey team scores 9 goals in their next game, it means that; the mean would be the most affected.

<h3>How to find mean, median and mode?</h3>

We are given the data set as;

3, 6, 2, 1, 2, 3, 0, 4, 5, 1, 5, 4.

Let us rearrange in ascending order to get;

0, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6.

The mean = (0 + 1 + 1 + 2 + 2 + 3 + 3 + 4 + 4 + 5 + 5 + 6)/12 = 3

Median = (3 + 3)/2 = 3

Mode = 1, 2, 3, 3, 5

Now, if they score 9 goals in their next game, it means that;

Mean = 45/13 = 3.46

Median = 3

Mode remains the same

Thus, mean will be the most affected.
