UNO [17]

Answer:

40 black ink cartridges and 19 colored ink cartridges

Step-by-step explanation:

Let b represent the number of black printer ink cartridges sold. Let c represent the number of color printer ink cartridges sold.

Set up a system of equations:

\displaystyle\\\begin{cases}b+c=59\\17.99b+20.99c=1,118.41\end{cases}

b+c=59\implies b=59-c

Substitute:

\displaystyle\\17.99(59-c)+20.99c=1,118.41\\\implies c=\boxed{19}

\implies b+19=59\implies b=\boxed{40}

⇒ 40 black ink cartridges, 19 colored ink cartridges (ans)

Hello!

Significant digits are defined as all digits that determine the value of a number, excluding any zeros that act as placeholders. Let's find the number of significant digits in each option individually:

A. 0.0009462 = 4 significant digits (the zeros are placeholders)
B. 1.000150 = 7 significant digits
C. 2.0145 = 5 significant digits
D. 3.01255 = 6 significant digits

Looking at the list above, we can see that Option B has the greatest number (7) of significant digits.

The answer is Option B.

I hope this helps!
