Question

To feed his plants logan creates a mixture that requires 3/8 cup of plant food for every gallon of water. If he uses 10 1/2 gallons of. Water what is the total amount of. Plant food he needa

Answer 1

`3\ (15)/(16)`

Explanation:

The mixture requires 3/8 cup of plant food for every gallon of water

Then it requires (10 1/2)×(3/8) cup of plant food for 10 1/2 gallons of water

Now we have to calculate (10 1/2)×(3/8)

`10\ (1)/(2) \ =\ (10* 2)/(2) +(1)/(2) \ =(20+1)/(2) =(21)/(2)`

`(21)/(2) * (3)/(8) =(63)/(16) =3\ (15)/(16)`

then he needs :

`(63)/(16)\ \ \text (cup\ of\ plant\ food)`
