16,900,000 in scientific notation is 16.9 times 10^7.
When you move the decimal point to the 1, it goes 7 spaces to the left, so the exponent will be a positive 7.
Am I too late to answer this
(A)
This is because you have to add $8 to your total bill, so you add 8 to the snacks you buy for you and your friend (2 x)
Also, 22 is the max amount you can use, and you don't add anything to your budget when you buy things.
Answer:
x = 1, y = 60
Step-by-step explanation:
Value of new-releases (x) = $20 each
Value of classic (y) = $8 each
Total budget = $500
Equation : 20x + 8y = 500
The librarian wants to purchase maximum DVDs. She can get more DVDs of classic movies for $8 as they are less costly.
Lets assume the librarian buys at least one new-release DVD.
x=1
20x + 8y = 500
8y + 20(1) = 500
y = 60
<em>Therefore, in a budget of $500, the librarian can purchase 60 classic movies and 1 new-release.</em>
