The Jokia Cell Phone Company manufactures two models of cell phones – the

Wombat and the Sloth. Each Wombat phone uses 2.5 ounces of gold leaf and 3 ounces of

plastic, whereas each Sloth phone uses 2 ounces of gold leaf and 2 ounces of plastic. Each day,

the company has only 370 ounces of gold leaf and 420 ounces of plastic to be used for making

cell phones. If the company makes the correct number of each type of phone on a given day to

use up all of the available gold leaf and plastic, how many Wombat phones will be made?
