Answer:

B. $5.58

Step-by-step explanation:

In order to find the amount of income earned, we can set up an equation using a variable for the number of checks and the minimum balance:

Income earned = (.008)b - $0.10c - $2.00, where b = the minimum balance and c = the number of checks.

Since the customer writes 21 checks, c = 21 and maintains a minimum balance of $1,210, b = 1210, we can fill in the variables and solve the equation:

Income earned = (.008)(1210) - (0.10)(21) - 2 or 9.69 - 2.10 - 2 = $5.58

Who started the problem correctly? The problem form is (-5) - (-1 3/4).

Veronika [31]

Answer:

Shane started the problem correctly

Step-by-step explanation:

We are given problem (-5) - (-1 3/4).

Mariah started the problem as (-5) + 1 - 3/4

Shane started the problem as (-5) + 1 + 3/4

We need to find who started the problem correctly.

The problem should be started by converting the mixed fraction into improper fraction i,e

$-5-(-1\frac{3}{4})\\=-5-(-1-\frac{3}{4} )\\=-5-(-\frac{7}{4})$

Now we will solve bracket by multiplying -1 with term inside the bracket i.e

$=-5+\frac{7}{4}$

$= \frac{-13}{4}$

Let's compare both the procedures now:

Mariah:

$(-5) + 1 - \frac{3}{4}$

$=(-5) - \frac{1}{4}$

$=\frac{-21}{4}$

Therefore, Mariah did not start the problem correctly.

Shane:

$(-5) + 1 + \frac{3}{4}$

$= -5 + \frac{7}{4}$

$= \frac{-13}{4}$

Therefore, Shane started the problem correctly.

The complete sentence should be:

Composite numbers can be written as a product of prime factors. This is called the prime factorization of a number.

A prime number is a number that can't be divided by any other number other than 1 or itself. Otherwise, that is a composite number. For example, 50 is a composite number. Through prime factorization,

50
/ \
10 5
/ \
5 2

The prime factors of composite number 50 are 5, 5 and 2.
