The result is $15,625
The full price represents 100%. A local college bookstore spent $12,500, which equates to 80% of the full price as this reflects a 20% discount (100% - 20% = 80%).
Now, let’s set up a proportion.
If $12,500 corresponds to 80% of the full price, what is the full price (100%):
$12,500: 80% = x: 100 %
x = $12,500 · 100% ÷ 80% = $15,625
All prime numbers are odd with the exception of two. Hence, if we consider the sum of the first million primes, it consists of one even number combined with 999,999 odd numbers. Since the product of an odd number multiplied by another odd number results in an odd number, we conclude that the sum must be an odd number, being even + odd = odd.
It's clear that an odd number ends with an odd digit, so the only digit that can be eliminated is b (an even digit).
Assuming a maximum rental duration of 8 days, if we apply this to the equation, Happy Harry's Rentals costs $500, while Smilin' Sam's charges $600. Therefore, for the 7th and 8th days, Happy Harry's Rentals is a better option, while Smilin' Sam's is preferable for the first six days.
Hi there!
While there are no answer choices provided, here's how you can solve a problem like this.
To find the average of two numbers, you simply sum them up and divide by two!
For instance, to find the midpoint between 1 and 3, you add 1 and 3 to get 4, then divide by 2 which results in 2!
For 100 and 580, adding gives you 680, and dividing by 2 results in 340!
The average between 0.57 and 0.69 involves adding to get 1.26, then dividing by 2 yields 0.63!
Now, with percentages, for 45% and 67%, the addition gives you 112%, and dividing that by 2 will result in 56%!
So, for your answer options, just calculate the total and divide by two to determine which one results in 76%!
I hope this information helps!
