Answer:
Amy has 12 5¢ coins
Step-by-step explanation:
Let <em>x</em> represent 20¢ coins and <em>y</em> represent 5¢ coins.
Amy has four more 20¢ coins than 5¢ coins. Hence:
And the total value of all her coins is $3.80. Thus:
This yields a system of equations:
We can solve by substitution. Substitute the first equation into the first:
Distribute:
Combine like terms:
And divide both sides by 0.25. Hence:
Thus, Amy has 12 5¢ coins.
Using the first equation:
Substitute:
Thus, Amy has 16 20¢ coins.
In conclusion, Amy has 12 5¢ coins and 16 20¢ coins.
Total amount of vegetables consumed per year are 208 pounds
So per month, the amount of vegetables consumed would be 208 divided by 12 which is the number of months in a year, so :
208 ÷ 12 = 17.3
So the average person ate 17.3 pounds of vegetables per month.
Likewise for the fruits we do the same calculation.
125 5/8 pounds can be written as 125.625 pounds when you make the fraction 5/8 into a decimal.
Now we divide by 12, so:
125.625 ÷ 12 = 10.47
So the average person ate 10.47 pounds of fruits per month.
Answer:

C.Strawberries
Step-by-step explanation:
In order to solve this we just need to find the amount of strawberries he picked, and if he picked 1 2/5 less in the morning and in the morning he picked 2 1/4, we just add that up to know how much he picked in the afternoon:
So in the afternoon he picked 
.
Now he picked 5 3/10 kg of tomatoes but 1.5 were rotten, we just have to withdraw the rotten from the total:
So now we know that he picked 
kg of good tomatoes.
If he picked in the afternoon and the morning 5.05 kg of strawberries, he picked more strawberries than tomatoes.
