To write the equation that represents the situation, we start with the total cost of the computer equipment of $675.95. The office manager bought one monitor for $127.95, and the hard drives are $68.50 each, where
Operations Involved:
- Addition: The cost of the monitor and the total cost of the hard drives is being added together.
- Multiplication: The cost of a single hard drive ($68.50) is multiplied by the number of hard drives purchased (
) to get the total cost of all hard drives.
We know these operations are involved because we have to add the cost of the monitor and the total cost of the hard drives to equal the total amount spent, which is $675.95.
Cost for 7 Hard Drives and 2 Monitors
To find the total cost for purchasing 7 hard drives and 2 monitors, we calculate:
- Cost of 2 monitors:
- Cost of 7 hard drives:
Now, add these two amounts together:
Therefore, the total cost for 7 hard drives and 2 monitors would be $735.40.
