Let's look at Jamal first. A is the number of trips Jamal makes. Jamal's container holds x gallons of water. In A trips, how much water does Jamal carry?
Jamal: 1 trip ---> 1 * x gallons = x 2 trips ---> 2 * x gallons = 2x 3 trips ---> 3 * x gallons = 3x ... A trips ---> ___ * x gallons = ____
Follow the pattern above. In A trips, how much water does Jamal carry?
A trips ---> 4 * x gallons = 4x ???
You gave me the next step in the pattern. If I want to know how much Jamal carries in 4 trips, he carries 4x. That is correct. That is not what I was asking, though. You did 4 trips ---> 4 * x gallons. Now we need to use the letter A to mean a number we don't know. Use A itself in the expression. In 4 trips ---> 4 * x gallons In A trips ---> ___ * x gallons What goes in the blank.
5? or a variable
A variable, and the variable we are using is A. A means the number of trips Jamal makes. |dw:1440042495958:dw|
Alright yes I get that
Ax + By ?
Jamal carries x gallons per trip. Jamal makes A trips. Jamal carries a total of Ax gallons. Now we do the same for Tanya. Tanya carries y gallons in each trip. Tanya makes B trips. Tanya carries a total of By gallons. The total carried by both Jamal and Tanya is Ax + By
Alright! See I was just a bit confused on what tanya and jamal were doing lo. Thanks for the help!
You're welcome. I hope that by breaking up the problem into Jamal's part and Tanya's part it made it easier for you to understand it.
It actually did! Thank again. @mathstudent55
Great. You're welcome.
