Emma works at a clothing store
where she gets an employee discount. If she paid 44 dollars and 87
for a pair of pants that costs 64 dollars and 10 cents, determine the percentage
Well, this question is a
percentage-change question cause we’re looking to see what the percentage change
is between our two values. And we have a formula to help
us. And that is that the percentage
change is the difference between the values divided by the original amount and
then multiplied by 100 to put it into a percentage. So, first of all, what we can
do is work out our difference. And it’s gonna be 64.10 minus
44.87 cause it’s 64 dollars 10 cents minus 44 dollars and 87 cents. Which is gonna give us 19.23,
or 19 dollars and 23 cents.
Okay, great, so now we can put
this into our formula. So, when we do this, we’re
gonna get our percentage discount is equal to 19.23 because that’s our
difference over and then our original amount. And that’s the price before the
sale, which is 64.10, or 64 dollars 10 cents. Then, we multiply the whole lot
by 100, which is gonna give us 30 percent. So therefore, we could say that
the percentage discount is 30 percent.
Now, what we can do is do a
quick check to check this is the correct answer. So then, before our check, what
we can do is do 64 dollars 10 because that was the original price. Then, multiply it by 0.7
because this would be our multiplier if we reduced by 30 percent. And this would give us 44
dollars and 87 cents, which is exactly what Emma paid. So, yes, this is correct.
