Answer: 31 cents
Step-by-step explanation: Since sales tax is 6%, in decimals, that is 0.06. Then you multiply the total of the bill by the tax amount to get how much she will be paying in tax.
5.20 x 0.06 = 0.312
Then you round to the nearest hundreth since you can't have a fraction of a cent to get 0.31
It means that there is one whole and another whole that is split into 10 pieces and one part(tenth) of that is filled in. That is what it means.
Answer:
1. x = 10 - y/2 2. x = 2 + 5y/6
Step-by-step explanation:
7. For this one, we need an equation. Lets make x = the price of the computer. Since the price of the printer is 30% the price of the computer, we can make that .3x, because a number multiplied by .3 will give you 30% of your original number. So, our equation will be:

Since x is the cost of the computer, you have your answer right there. The computer costs $2,028.
8. For this one we're going to need a proportion, but first we need to find out how much of the percentage of seeds Cliff planted.
% of seeds planted per person:
Ali - 40
Ben - 45
Cliff - x
All percentages add up to 100, so we'll make an equation to figure this out:

Therefore, Cliff planted 15% of the seeds. Since Cliff planted 15% of the seeds, and he planted 87 total, 15% of our total number of seeds planted is 87. We can now make a proportion to figure out how many seedlings were planted all together.

We can now cross multiply in order to get a solvable equation:

The total number of seedlings planted was 580.
Sorry if this is confusing at all, hope I helped!
