What single decimal multiplier would you use to increase by 9% followed by 3% decrease
MaRussiya [10]

Answer:

= 94

Step-by-step explanation:

To work out the multiplier, first add or subtract the percentage from 100, then convert to a decimal. Example: we want to add 20% to £110. To work out the multiplier, add 20 to 100, to get 120, and then change it to a decimal (divide by 100) to get 1.2. The answer is £110 x 1.2 = £132.

so to workout an increase of 9% followed by 3% we would do:

9% - 3% = 6%. convert = 0.06 = 100-6 = 94 converted into 0.94 x 100 = 94

David sells two calculators for ₹1500 each .He earns a profit of 25% on
notsponge [240]

Answer:

gain = 0

% = 0

Step-by-step explanation:

<em><u>Profit</u></em>

He sells one for a profit of 25% That means he sells one of them for 100% + 25% = 125%

₹1500 * 125/100 = ₹187500/100 = ₹1875

<em><u>Loss</u></em>

Here he sells it for 25% less than the selling price he wanted.

100% - 25% = 75%

₹1500 * 75/100 = ₹112500/100 = ₹1125

<em><u>Discussion</u></em>

He should make ₹1500 + ₹1500 = ₹3000 without either profit or loss.

What he actually accomplishes is ₹1125 + ₹1875 = ₹3000

So he has a net gain (loss) of 0.

The % is 0

Jana And Jordan had 23 oranges Jana had 7 fewer oranges than Jordan how many oranges did each girl have
Solnce55 [7]

Answer:

Jana had 8 oranges, and Jordan had 15 oranges.

Step-by-step explanation:

First, identify what you know:

1) In total, Jana and Jordan had 23 oranges.

2) Jana had 7 less oranges than Jordan.

We can create a formula, where x equals the number of oranges Jana has.

23 = x + (x + 7)

16 = x + x (subtracted 7 from both sides)

x = 8 (divided both sides by 2)

So, now we know Jana had 8 oranges, which is 7 less than Jordan.

8 + 7 = ?

? = 15

Jana had 8 oranges, while Jordan had 15, for a total of 23 oranges.
