Iwent to a store i saw different cat food for my cat 1 is 8 lbs for $16 second is 5 lbs for $12: 99 third one is 8lbs for $17 and the fourth one is $ 18.99 how will i figure which cat food that gives me the most for my money,how will i calculates it

For each one, divide the quantity by the cost, to get the "unit cost".

#1:  8 lbs / $16  =        0.5     pound per $

#2:  5 lbs / $12.99  =  0.385 pound per $
 
#3:  8 lbs / $17  =       0.471 pound per $ 

#4:  P lbs / $18.99  =  P/18.99 pound per $

Step-by-step explanation:

To get at least $420 with the babysitting job, you have to work 35 hours a week which if you work 5 days a week, you will have to work 7 hours a day, but if you were working 7 days a week, you would have to work for 5 hours a day.

To get at east $420 with the cleaning job, you have to work 28 hours a week. If you worked 5 days a week, you would have to work 5.6 hours a day, but if you worked 7 days a week, you would only have to work 4 hours a day.

Either way, the cleaning job pays more per hour, which means that you would have to work less hours to get the same amount of money that you would get for babysitting.
