Solve for q:

q=6

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

-30q+8r=-124

-30*6+8r=-124

Solve for r:

1. Round to the nearest cent.
$10.456
$11.00
$10.50
$10.45

Answers

the correct answer is ^

10.46

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

.465

If a number is 5 or above, it rounds up, if it’s lower than 5 it rounds down

The rounding only affects the 6, since the 6 rounding would affect the 4
