Answer:
56
Step-by-step explanation:
Firstly, we know she sold 24 hot dogs at half price. We do not know the total number of hot dogs.
Secondly, we know that 30% of the hot dogs were sold at half of the price. This means 70% were sold at full price.
Now there are two approaches to this. I'm going to take the easier one.
What we are expressing mathematically is that 30% of a certain number equals 24. Let the total number of hot dogs she had that day at her stand be x.
This mean 30% of x = 24.
30/100 × x = 24
30x = 24× 100
30x = 2,400
x = 2,400/30 = 80.
This means she had a total of 80 hot dogs that day. Since we know the number she sold at half price, it's now easy to calculate the number she sold at full price.
This number now equals 80 - 24 = 56 hot dogs.
This mean Mandy sold 56 hot dogs at full price.
Answer:
-336
Step-by-step explanation:
g(x) = 24(x − 39)
Let x = 25
g(x) = 24(25 − 39)
= 24 (-14)
= -336
Answer:
=5xy−9x−9y+7
Step-by-step explanation:
Let's simplify step-by-step.
−6x+5xy−9y−3x+7
=−6x+5xy+−9y+−3x+7
Combine Like Terms:
=−6x+5xy+−9y+−3x+7
=(5xy)+(−6x+−3x)+(−9y)+(7)
=5xy+−9x+−9y+7
Answer:
=5xy−9x−9y+7
Answer:
The answer is 1.62%
Step-by-step explanation:
A credit card issuer charges an APR of 19.66%
The billing cycle is 30 days
We have to find the periodic interest rate. The periodic rate is found by dividing the APR by the number of billing periods in the year.
The value here becomes:
= 1.615%≈1.62%
Hence, the answer is 1.62%
Hope this helps:)
Multiply the numerator and denominator of 23/25 by 10 and do the same on 9/10 but multiply by 25. Your denominator will be 250. You can figure the rest out.
