Each small kite costs $4, while each large kite costs $7. if the total money collected selling kites is $150, and 30 kites are sold, which system of equations can be used to find out how many of each size kite are sold? let s be the small kites and l be the number of large kites. a. 4l+7s=150 s+l=30 b. 7l+4s=150 s+l+30 c. 7l+4s+30 s+l=150 d. l+4s=150 s+7l=30
