sports store sells three different packs of tennis balls. Brand A costs $2.50 for two balls, brand B sells three balls for $3.90, and brand C has a sale of four balls for $5.12. Which inequality about the unit price per ball is correct
To answer this question you need to convert the 48 inches first to feet, as fabric is sold by the foot. 48 in converts to 4 ft which is what we will use for each curtain. Since we need 46 curtains we will multiply 46 curtains by 4 feet which will give our answer of 184 feet.
