Answer: 50 Books
Step-by-step explanation:
B = number of books in Ruben's collection BEFORE he bought new ones.
So 6 books were bought which increased his collection by 12%.
12% as a decimal would be 0.12..then we add the variable which represents the number of books, 0.12B.
So then we know 0.12=6
*We need to isolate the variable* So we would divide 0.12 on both sides. 0.12/0.12 and 0.12/6 which is 50.
Hope this helps! :)
Grocery store : 2.80/8 = 0.35.....so its 35 cents per oz.----0.35(16) = 5.60 per lb
farmers market : 4.20/14 = 0.3...so its 30 cents per oz --- 0.30(16) = 4.80 per lb
5.60 - 4.80 = 0.80.....answer is : blueberries are 80 cents per pound less expensive at the farmers market
Answer:
x = 0
Step-by-step explanation:
6(x + 1) -5x = 8 + 2(x - 1)
6x + 6 - 5x = 8 + 2x - 2
6x - 5x - 2x = 8 - 2 - 6
- x = 0
