What is the minimum number of selections from the set { 1, 3, 5, 7, 9, 11, 13, 15 } that we need to guarantee that at least one
anygoal [31]
Perhaps I don't understand the question. You only need to choose one pair that adds to 16, any of {1, 15}, {3, 13}, {5, 11}, {7, 9}.

You can choose up to 4 numbers without getting a pair that adds to 16, so if you choose any 5 numbers, at least one pair of them will add to 16.

Groceries cost $75. The tax is 5%. Will you have enough money to pay for the groceries if you have $80. Please explain.
Nastasia [14]

Answer:

Yes, we have enough money to pay for the groceries.

Step-by-step explanation:

We are given that Groceries cost $75. The tax rate is 5%.

We have to check that will the amount of $80 enough to pay for the groceries or not.

<em>For this we will firstly calculate the total cost of groceries after applying tax rate of 5% on groceries. </em>

Cost of groceries after applying tax rate is given by;

Since we know that by applying a tax on any item it's cost gets increased.

So, <u>Cost of groceries after tax</u> = Cost of groceries before tax + Amount of tax      

Amount of tax = Tax rate \times Cost of groceries

                        = 5% \times $75

                        = \frac{5}{100} \times 75 = $3.75

So, Cost of groceries after tax = $75 + $3.75 = $78.75

Since we have an amount of $80 with us which means that we are able to buy the groceries after giving tax on it as $78.75 < $80.

Therefore, yes we have enough money to pay for the groceries.

Why is it important to use estimation when solving problems
stellarik [79]
Well, it might not be important for most problems but..
If you're dividing, and the answer is a repeat..
You can estimate.

Example - 2.678 | You can estimate it to 2.68 and use that as an answer instead of a very long answer that's repeated.

I hope this helps.
