Question

Naomi works at a feed store, and today she is unpacking bags of birdseed. She knows each bag has a mass of 7.5 kg and that they are in a crate that has a mass of 35 kg. If the total mass is 200 kg, how many bags of birdseed are in the crate?​

Answer 1

To find the number of bags of birdseed in the crate, subtract the combined mass of the crate and bags from the total mass. Then, divide the combined mass of the bags by the mass of each bag.

Step-by-step explanation:

To find the number of bags of birdseed in the crate, we need to subtract the combined mass of the crate and the bags from the total mass. The crate has a mass of 35 kg and each bag has a mass of 7.5 kg. So, the combined mass of the bags will be 35 kg less than the total mass. We can find the number of bags by dividing the combined mass of the bags by the mass of each bag. Let's calculate it:

1. Total mass = 200 kg
2. Combined mass of crate and bags = 35 kg
3. Combined mass of bags = Total mass - Combined mass of crate and bags = 200 kg - 35 kg = 165 kg
4. Number of bags = Combined mass of bags / Mass of each bag = 165 kg / 7.5 kg = 22 bags

Therefore, there are 22 bags of birdseed in the crate.
