Gambelli agency rents cars for $40 dollars per day plus 25 cents for every mile driven. Mcdougal rental rents cars for $58 per day unlimited mileage. How many miles a day can you drive a gamebelly agency car if it is cost you less than a mcdougal rental cars?
I got 58-40=18
18 X .25 = 72 miles
is this right?
How many ounces of pure water must be added to 60 oz of an 8% salt solution to make a 3% salt solution.
let's x be the pure water that should be added
I got .8(60)=4.8
4.8/60+x = 3/100
is this right so far?
