L = pounds of lollipop
c = pounds of caramel candies

0.95l + 1.10c = 30 ($0.95/lb & $1.10/lb)
l + c = 30 (mixture sells for $1/lb)
c = 30 - l

0.95l + 1.10(30 - l) = 30 (Substitution)
0.95l + 33 - 1.10l = 30
-0.15l = -3 (move terms)
l = 20lbs

Hope this helps.

Answer:

Completing the table, we have;

Explanation:

Given the equation;

$y=2x-1$

where y is the output and x is the input.

we were given the outputs 1,3,5.

To get the input for each of the given output let us substitute the output into the equation and solve for x;

$\begin{gathered} \text{for output = 1;} \\ 1=2x-1 \\ 1+1=2x \\ 2=2x \\ x=\frac{2}{2} \\ x=1 \end{gathered}$ $\begin{gathered} \text{for output = 3 ;} \\ 3=2x-1 \\ 3+1=2x \\ 4=2x \\ \frac{4}{2}=x \\ x=2 \end{gathered}$ $\begin{gathered} \text{for output = 5;} \\ 5=2x-1 \\ 5+1=2x \\ 6=2x \\ \frac{6}{2}=x \\ x=3 \end{gathered}$

Therefore, completing the table, we have;
