The Ortiz children were each given $20 spending money. By the end of day two, Joe had spent 7/8 of his money, Lila had spent 3/4 of her money, and Anton had spent 3/5 of his money. How much money did the Ortiz children spend altogether?
20 *(7/8) + 20 * ( 3/4) + 20* (3/5) = $............ spent
or 20 * ( 7/8 + 3/4 + 3/5) = $.............. spent
