Express each situation as an algebraic expression:
1. An electric company charges $10 a month plus $.15 per kilowatt-hour of electricity used. What is the monthly bill in dollars if K kilowatt-hours are used?
monthly bill = 10 + 0.15K
6 dollars for 8 cans of vegtables
To express the given situation as an algebraic expression, we need to identify the components involved and formulate the expression accordingly.
Here are the components mentioned in the situation:
- Cost per month (base cost): $10
- Cost per kilowatt-hour (usage cost): $0.15
- Number of kilowatt-hours used: K
To calculate the monthly bill in dollars, we need to multiply the number of kilowatt-hours used by the cost per kilowatt-hour and then add the base cost:
Cost per kilowatt-hour * Number of kilowatt-hours used + Base cost
Using the given information, we can now create an algebraic expression:
0.15K + 10
Therefore, the algebraic expression for the monthly bill in dollars is 0.15K + 10.
