$11.00
$10.50
$10.45
$10.46

Answers

the correct answer is ^

10.46

Ignore the 10, since it is only to the nearest cent and it doesn’t matter

Answers

q= 6

work--

Multiply 1st column by -2:

5q+8r=86

Subtract 2nd column from the first column:

-35q= -210

Solve for q:

q=6

Subtract q=6 by any of the two equations, so:

-30q+8r=-124

-30*6+8r=-124
