Last night, Jim bought a $7 lamp and a bulb which cost $4 less. If he bought 2 lamps and 6 bulbs, how much did Jim pay in all?
Thoughts? Step-by-step reasoning:
User
The cost of the bulb is $7 - $4 = $3. The cost of 2 lamps is $7 x 2 = $14. The cost of 6 bulbs is $3 x 6 = $18. Jim paid a total of $14 + $18 = $32.
Thus, the answer is 32.
