Answer 2

Let's calculate the mean of the 5 lunches in the first week. We calculate the mean by adding all the numbers up and dividing by how many numbers there are. So we have:


`\sf(12.48+9.50+10.25+4.99+8.59)/(5)=9.162`

So this is the mean of the 5 lunches in the first week. We are told that in the second week he spent $3 more on his 5 lunches, let's calculate the mean of the second week:


`\sf(12.48+9.50+10.25+4.99+8.59+3)/(5)=9.762`

This is the mean for the second week. Subtract it from the mean in the first week to find the increase:


`\sf 9.762-9.162=\boxed{\sf\$ 0.60}`
