Dey get 10 boys for the class and each boy bring 5 cups for science activity class as Ms. Leech tell dem. If the total number of cups wey the students bring for the class na 90, how many cups each girl bring?``` <response>: If Ms. Leech get 30 students for her class, and the number of boys na 10, the number of girls for Ms. Leech class na 30-10=20
If each boy carry 5 cups for the science activity, the total number of cups wey boys carry na 5*10=50 cups.
The number of cups wey girls carry na 90-50=40 of the total number.
Since the number of girls for the class na 20, each girl carry 40/20=2 cups each.
