Ruby wants to start her own business taking photographs. She already has her own camera, but needs to purchase lights, a photo printer, and photo paper. If the cost of the photo printer is $251.99, the cost of lighting is $150.00, and the cost for 100 sheets of photo paper is $30.98, determine how much of her savings will be used to start her company, given that she has $840.32 in savings.
Add the costs of the items Ruby needs: $251.99 + $150.00 + $30.98 = $432.97. So she will use $432.97 of her savings to start her company; the $840.32 is her total savings, not the amount she spends.
