Question

Help me solve this question pls

Answer 1

15%

Explanation:

Formula to find percentage increase/decrease/multiplier:

NV = OV x m

In words: New value = Old value x multiplier

In this question we're looking for the m (multiplier), so rearrange the formula and make m the subject.

m = NV / OV

So NV is the increase: 3162.50

OV = 2750

So 3162.50 / 2750 = 1.15

This is the multiplier (1.15) so turn into percentage by multiplying by 100 then subtract by 100.

1.15 * 100 = 115 - 100 = 15%

And the fact that the number is postive is proof that price has increased, if it was decrease, you would be expecting a negative number. Hope you understood. :)

Answer 2

Answer: 15%
Because 3162.50 divided by 2750 is 1.15
1.15 x 100 is 115%
115-100 = 15% increase
