if you divide $7.20 by 4 your get $1.80 which is how much she gets paid for 1/5 of an hour. To get how much she gets in an hour just multiply $1.80 by 5 which is $9.00
I honestly don’t even know how to explain this- but ik that 3 should be alright to type in bc if you were to write it on a graph you would move 1 unit to the right and 3 units up from there based on the coordinates after the origin (0,0).
