During the day, sam spent $4.85 on lunch. he also bought 2 books for $7.95 each. at the end of the day, he had $8.20 left. how much money did he start with?

Hey!~

So what you would want to do is add the amount he spent onto the amount he was left with. $8.20 + (2*$7.95) + $4.85 = $28.95

Hope this helps and have a great day!

I’m going to infer you said parallel.solve for yy= -1/2x+7/4lines that are parallel have the same slope, different y intercept.so we know m is -1/2then from there solve for y intercept.
