So, we write a fraction, which would be 12/100. Then we would do 12/100 = x/550. You could divide 100 by 550, which is 5.5. Then we would multiply 5.5 by 12, which is 66. So 66 people would be wearing glasses.

The solution of the equation is given by (-2,-1), This is represented by option C.
<h3>What is a System of Equations?</h3>
A system of equations is a set of equation that have a common solution.
The solution of the equations can be determined by using the Elimination and Substitution method
3x-5y = -1
2x-y = -3
-7x = 14
x = -2
Substituting this value in the equation
3 * (-2) -5y = -1
-6 -5y = -1
-5y = 5
y = -1
Therefore, the solution of the equation is given by (-2,-1), This is represented by option C.

A. 200.625 minutes B. 184.166 minutes C. 200 minutes (round these answers like the question asked) 4. Plan A is the best because you get the most minutes for your money. I will explain my work for A, but if you need to explain the rest just ask. So, if you have to pay $3.95 every month no matter what and $0.08 for every minute you talk you can write the equation as, Cost = 3.95 + 0.08m (m stands for minutes), and the cost is 20$ then the equation is 20 = 3.95 + 0.08m, subtract 3.95 from the right side to make it 16.05 = 0.08m, then divide everything by 0.08 to get m, which gives you m= 200.625
