Denny uses 81 gallons of water to wash 12 dogs. If the amount of water used varies directly with the number of dogs washed, how many gallons of water will be needed to wash 42 dogs? Assume that the number of dogs washed is the independent variable.

mark has $52

d. 5.43x1012 h.5.43e12

ok ur answer is 290 1/2 miles

because all u need to do 83*3 1/2 because u would multiply it by 5 1/2 but the 83 miles was after 2 mikes they did not say 5 more miles all they said was after 5 1/2 miles

assuming "divided his salary into two" means in half,

he has 215 remaining, plus 200 he originally had before buying a watch

he originally has $415 in his personal account

if this is half the salary, 415 times 2 is $830

his salary would have been $830.
