It says what is the scale factor but there are no number! or

DFN's sides are twice as big as GHM's, therefore, the scale factor is 2. You just need to type in a 2 in the box

42 inches then 10 1/2 deep

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
