John works 40 hours a week as a carpenter. He spends 60% of this time building decks and 40% installing siding. John is paid a different hourly wage for each type of labor. Let x represent the hourly wage for building decks and y represent the hourly wage for installing siding. Which expression represents John's weekly income?

16x+24y
0.4x+0.6y
0.6x+0.4y
24x+16y

60% of this time building decks ... 60% of 40 hrs is 24 hrs

x is the hourly wage for building decks
So, it must be D

Is anyone else panicking from this exam?

To calculate John's weekly income, we need to multiply the number of hours he spends on each type of labor by the respective hourly wage.

Let's break it down step by step:

- John spends 60% of his time building decks. To calculate his income from building decks, we multiply the number of hours he spends building decks (which is 60% of 40 hours) by the hourly wage for building decks, x. This gives us (0.6 * 40 * x) or 24x.
- John spends 40% of his time installing siding. To calculate his income from installing siding, we multiply the number of hours he spends installing siding (which is 40% of 40 hours) by the hourly wage for installing siding, y. This gives us (0.4 * 40 * y) or 16y.

Finally, we add the income from building decks and installing siding together to get John's weekly income:

Income = 24x + 16y

Therefore, the expression that represents John's weekly income is 24x + 16y.
