A 4-pound bag of potatoes costs $3.16 how much would 32 pounds of potatoes costs
zimovet [89]

Answer:

$25.28

Step-by-step explanation:

Since a 4 pound bag cost $3.16 you would do 32 divided by 4 and you would get 8. Then you would do 8 times 3.16 and you get 25.28.

The long way:
4 bags = 3.16
8 bags = 6.32
12 bags = 9.48
16 bags = 12.64
20 bags = 15.80
24 bags = 18.96
28 bags = 22.12
32 bags = 25.28

Jeffrey currently has an account balance of $1,565.00. His initial deposit on the account was $625 and it earned 4.7% simple int
hram777 [196]
A = P(1 + rt)

1565 = 625(1 + (0.047)(t))

2.504 = 1 + 0.047t

1.504 = 0.047t

t = 32

I hope this is correct! (Sorry I haven't done simple interest in a while.)

Round off 787592799 to the nearest 10​
timama [110]

Answer:

787592800

Step-by-step explanation:

Hi there,

If you round this answer to the nearest tens place, it would be 787592800. Since the 799 is closer to 800 rather than 790, it would round up and change the last three digits of the number instead of the usual two digits.

Hope this answer helps. Cheers.
