Answer:
A) 29 plants
B) $90.75
Step-by-step explanation:
A) Divide 79.75 by 2.75. It will give you the plant number.
B) Multiply 4 and 2.75 which should equal 11. Add that to 79.75.
Good Luck!!!!!!!
A = first number (larger number)
b = second number (smaller number)
a = 8b
a - b = 70 *
* since a is the larger number and their difference is positive, we want a-b.
plug the first equation into the second to get :
a - b = 70
(8b) - b = 70
8b - b = 70
Your correct answer would be choice #2.
