Answer:
Jenny packaged 12 eggs per carton
Step-by-step explanation:
we know that
To find the rate divide the total amount of eggs by the total number of cartons
so

therefore
The statement is
Jenny packaged 12 eggs per carton
21/1 divided by 7/4 = 21/1 x 4/7 = 12.
Hope this helped my guy.
9x+15=8x
subtract 15 and 8x from both sides to get
x=-15
