Answer 1

$\text{Turn the scenario into an equation:}\\\\y=2x+3\\\\\text{x = hours}\\\\\text{Solve for the different hours:}\\\\\text{A. 2 hours:}\\\\y=2(2)+3\\\\y=4+3\\\\\boxed{y=\ 7}\\\\\text{B. 4 hours}\\\\y=2(4)+3\\\\y=8+3\\\\\boxed{y=\ 11}\\\\\text{C. 3 1/2 hours}\\\\y=2(3.5)+3\\\\y=7+3\\\\\boxed{y=\ 10}$
