Let x= number of avocadoes she can buy
let y= total cost
y= 2x
9= 2x 9/2= 4.5
4.5= x
(you cannot cut the avocado in half therefore your answer is simply 4)
0.9% / 100% = 0.009
= 9/1000
equivalent ratio:
9/1000 = 153/x
cross multiply
9x = 153,000
x = 153,000/9
x = 17,000
153/17,000 = 0.009
Answer:
7%
Step-by-step explanation:
31 + 371 + 21 = 423
31/423 = 7%
3 lbs at 4.50 per lb = (4.50 * 3) = 13.50 <==
