Question

# At a restaurant, *n *cups of tea are made by adding *t *tea bags to hot water. If *t n *= +2, how many additional tea bags are needed to make each additional cup of tea?

- None
- One
- Two
- Three

## The correct answer is: One

### Solution :

n = The number of cups of tea

t = The number of tea bags

t = n + 2.

For n = 1,

t= 1 + 2 =3

For n = 2,

t = 2 + 2 = 4

For n = 3,

t = 3 + 2 = 5

And so on.

This follows a pattern. For 1 unit increase in n, t is also increasing by 1.

So we can see for each additional cup of tea, 1 additional tea bag is needed.

Therefore option (B)One is correct.

In 1962, the population of a bird species was 2,000. The population *k *years after 1962 were 48, and *k *satisfies the equation above. Which of the following is the best interpretation of the number 61 in this

context?

**Note:**

This question could also be solved by eliminating the options. Option A is wrong as the population *k* years after 1962 is 48, not 61. Option B is wrong because we find the value of k to be 32. Option C is wrong because the difference between the population in 1962 and the population *k *years after 1962 is given by 2000-48=1952.

One method of calculating the approximate age, in years, of a tree of a particular species is to multiply the diameter of the tree, in inches, by a constant called the growth factor for that species. The table above gives the growth factors for eight species of trees.

If a white birch tree and a pin oak tree each now have a diameter of 1 foot, which of the following will be closest to the difference, in inches, of their diameters 10 years from now? (1 foot = 12 inches)

In the equation above, c is a constant. If the equation has infinitely many solutions, what is the value of c ?

**Note: **

As the equation is true for all values of x, we could have put x equal to any other number instead of 1, and we would get the same result. If we put x=1 in the first step as well, we would get the same value for x
