Question

Lin needs 240 feet of wood to replace
the flooring in her dining room. She has 32 pieces
of oak and 36 pieces of pine. Each piece of oak is
2.25 feet long and each piece of pine is 2.5 feet
long. How much more wood does Lin need ?

Verity · Answer

Answer:   78 feet   Step-by-step explanation:   32 pieces of pine at 2.25 feet each works out to total of 32 x 2.25 = 72 feet  36 pieces of oak at 2.5 feet each works out to total of 36 x 2.5= 90 feet  Total amount of wood that Lin has already = 72 + 90 = 162 feet  Since she needs 240 feet of wood, she is short by 240-162 = 78 feet
