25 ham barbecue sandwiches and 12 drinks cost \$83.75. 50 ham barbecue sandwiches and 27 drinks cost \$171.25. What is the cost of each sandwich?

You might want to edit your latex so people can clearly read the post.

25H + 12D = 83.75

50H + 27D = 171.25

Double every term in the 1st equation, then subtract from the 2nd ... solve for D, the cost of a drink, then determine the cost of a sandwich, H.

A man just finished painting his house and needs something more.
At the hardware store, the clerk shows him what he wants and says, "one is \$1."
"Fine," says the man, "I took 600, so here's \$3."
What had he bought?
Thanks from Greens
