Ian buys 4 bananas and 2 apples. Each banana has a mass of 120 grams. Each apple has a mass of 180 grams.
Which is the total mass of the fruit that Ian buys?
A.300 grams
B.580 grams
C.840 grams
D.960 grams
The total mass of bananas is: 4 bananas * 120 grams/banana = 480 grams
The total mass of apples is: 2 apples * 180 grams/apple = 360 grams
The total mass of fruit is: 480 grams + 360 grams = 840 grams
Therefore, the answer is C. 840 grams.
To find the total mass of the fruit that Ian buys, we need to calculate the individual masses of the bananas and apples, and then add them together.
Each banana has a mass of 120 grams, and Ian buys 4 bananas. So the total mass of the bananas is 120 grams x 4 = 480 grams.
Each apple has a mass of 180 grams, and Ian buys 2 apples. So the total mass of the apples is 180 grams x 2 = 360 grams.
Now we add the mass of the bananas and apples together: 480 grams + 360 grams = 840 grams.
Therefore, the total mass of the fruit that Ian buys is 840 grams.
Answer: C. 840 grams
