Problema Solution
Dan orders supplies for the science lab. Each of the 18 stations in the chemistry lab needs 4 feet of rubber tubing. If rubber tubing sells for $7.75 per yard, how much will it cost to equip all the stations?
Answer provided by our tutors
The lab will need total of 18*4 = 72 ft of rubber tubing.
1 yd = 3 ft
1 ft = 1/3 yd
72 ft = 72/3 yd = 24 yd
$7.75*24 = $186
It will cost $186 to equip all the stations.
