Step-by-step explanation:{(A,3),(B,4),(C,5),(,D,9),(E,10)}
5 trays × 30 eggs/tray = 150 eggsEach cake requires 8 eggs;150 eggs ÷ 8 eggs/cake = 18.75 cakesSince you can't bake a fraction of a cake, the baker can make:18 cakesHow many eggs are left:150 eggs - (18 cakes × 8 eggs/cake) = 150 - 144 = 6 eggsSo, the baker can make 18 cakes and has 6 eggs left.Hope it helped you!!
