Question

Jorie is collecting rain water in 30 gallon and 50 gallon barrels. f represents the number of full 30 gallon barrels and g represents the number of full 50 gallon barrels.

Which expression describes the total volume of water collected?

Answer 1

You can ask yourself what 10 full 30 gallon barrels means in terms of numbers
(30*10=300)


Again 10 full 50g barrels = 50*10 = 500

Answer 2

What would the total of 10f + 10g?

Answer 3

still confused

Answer 4

if f is the number of full 30g barrels
than
1f=1*30
2f=2*30
3f=3*30

do you see a pattern?

Answer 5

we set f equal to any number. To get the number of gallons, we multiply f by 30.

To get the total gallons in g we multiply by 50 because EACH barrel is 50 gallons.

Answer 6

ohh thank you
