Denver uses 7 pieces of wood for each birdhouse and he pays $1.50 for each piece of wood. If he makes a $5.50 profit per birdhouse, how much will Denver charge to Danny for buying two birdhouses?

How much does it cost to make one birdhouse? ** The cost for making one birdhouse is $1.50 x 7 = $<<1.5*7=10.50>>10.50.
How much does it cost to buy one birdhouse? ** So the selling price of one birdhouse is $10.50 + $5.50 = $<<10.5+5.5=16>>16.
How much will Denver charge Danny for buying two birdhouses? ** Thus, Denver will charge Danny $16 x 2 = $<<16*2=32>>32 for the two birdhouses.
