(0.7p)=p-250
30% off of p must be equal to 250 less than p. As a result you can say that 0.7p (0.7Xp), which is 70% of p (100%-30%=70%) is equal to p-250, so 0.7p=p-250.
Answer:
f x d = d x f
The commutative property of multiplication is just the numbers switched around, but it doesn't change the product. It has to in multiplication.
FYI, that L in the denominator is factorial.
This is some pretty serious stuff for high school.
My inclination is that the answer is A, which is the definition of <em>e. </em> Let's see if we can show this.
Let's write
Let's expand this with the binomial expansion
Let's focus on when n is really big and on the ks that are relatively small, which make up the bulk of the sum as the terms get small rapidly.
Then that numerator n(n-1)···(n-k+1) ≈ n^k as all the factors are about n.
OK, we showed for large n this is approximately true, and it will be exactly true in the limit, so we choose

Answer: $293.28
Step-by-step explanation:
We know that 282 is the 100% price tag on the bicycle. And there is a 4% tax applied to the 282. So we need to find out how much is 4% of 282.
282/100% = x/4% (we don’t know how much is 4% so its represented by X.
do a cross over where you end up with this:
282 (4) = x (100) we want to have X on its own as it represents the 4% to which we are looking for the amount in dollars. So you end up with this:
282 (4) /100 = x
solve the multiplication first and then divide.
1128/100 = x
11.28 = x
so now we know 4% of 282 is $11.28 so we add it to know how much does this person pay.
$282 + $11.28 = $293.28
