Answer:
Step-by-step explanation:
5 gallons is 1/10 of 50 gallons; this is 10% of capacity.
30 gallons 30/50, or 60%
45 gallons 45/50, or 90%
100 gallons 200%
So, the dog eats 5 cups a day and 1 pound of dog food is 10.5 cups.
A 50 lb bag is<span> $22.50.
Since you're asking how much it would cost to feed it a day we need to find out how much 1 pound of food costs.
</span>22.50 / 50 = 0.45
So, it's 0.45 for 1 lb. But 1 lb is 10.5 cups, not 5.
0.45 / 5 = 0.09
So, I believe it would cost 0.09 each day to feed the dog.
A: We want to take away all the useless numbers that don’t relate to the notebook first, and subtract them.
75 - 6 = 69
69 - 12 = 57
There, now we have to subtract the amount of money she has when she leaves from the total amount spent right now.
57 - 39 = 18
To get the amount spent on all four notebooks, all you need to do is divide by 4
18 / 4 = $4.50
And that’s your answer!
B: $4.50
