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?

How much does the bulb cost? ** The cost of the bulb is $7 - $4 = $<<7-4=3>>3.
How much do the lamps cost? ** The cost of 2 lamps is $7 x 2 = $<<7*2=14>>14.
How much do the bulbs cost? ** The cost of 6 bulbs is $3 x 6 = $<<3*6=18>>18.
How much did Jim pay in all? ** Jim paid a total of $14 + $18 = $<<14+18=32>>32.
