Answer from: c4thegoat

The sale price of the item is 96 pounds.

Step-by-step explanation:

If all the items are reduced by 20%, this means now their price is 100% - 20% = 80% of the original price.

Therefore, if an item was originally priced at 120pounds, its price now will of 80% of 120 pounds, i.e.

$\text{Sale price} =\dfrac{80\%}{100\%}*120 \pounds$

$\text{Sale price}=0.8*120 \pounds$

$\boxed{ \text{Sale price} =96 \pounds}$

The sale price of the item is 96 pounds.

Answer from: ayoismeisjjjjuan

£96

Step-by-step explanation:

Let new price be N_p

Sale price reduction rate=20%

Initial Item price=120

The new price will be reduced by a margin of 20%. Therefore the new price is obtained by multiplying old price by (100-20)%.

$I_p=120\\r=20\%\\N_p=I_p(1-r)\\N_p=120(1-0.20)\\N_p=96$

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

$4/2 = 2\\7/3.5=2\\8/4=2\\10/5=2$

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

$y=\frac{x}{2}$

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
