He began with 10. Because if he bought 8 after selling half of his books and now his total is 13, then 13-8=5
so 5+5=10
Answer:
He can buy 160 crates of apples and 40 crates of pears. (160, 40).
Step-by-step explanation:
From the information given, you can write the following equations:
25x+25y=5000 (1)
6x+5.50y=1180 (2), where:
x is the number of crates of apples
y is the number of crates of pears
First, you can solve for x in (1):
25x=5000-25y
x=(5000/25)-(25y/25)
x=200-y (3)
Then, you can replace (3) in (2) and solve for y:
6(200-y)+5.50y=1180
1200-6y+5.50y=1180
1200-1180=6y-5.50y
20=0.5y
y=20/0.5
y=40
Finally, you can replace the value of y in (3) to find the value of x:
x=200-y
x=200-40
x=160
According to this, the answer is that he can buy 160 crates of apples and 40 crates of pears. (160, 40).
You need to know the difference in change between .40 and 7.25, which is 6.85, then you divide the change in price by the original amount, so you do 6.85/.40, which is 17.125, then multiply by 100 to get percent and you get 1712.5% increase.
Answer:
4 cups of mayonnaise.
Step-by-step explanation:
The ratio of the amount of pecans comparing reality and the recipe is:
1 : 3/8
= 1/(3/8)
= 8/3
Hence, to find the amount of mayonnaise that should be added:
8/3 * 3/2
= 8/2
= 4 cups
Hope this helped!
You gave me numbers but forgot the question. Without a question there is no answer.
