How do i create a graphical representation of the data given? it’s a word problem: my brother and i both go to the stores on black friday, and spend 4 hours shopping. between the two of us, we spend a total of $400, and my brother spent $80 more than i did. how much money did each of us spend?

Let $x be the amount of money you spent and $y be the amount of money your brother spent.

1. You both spend a total of $400, then

x+y=400.

2. Your brother spent $80 more than you did, then

y=x+80.

Consider the system of two equations:

The graphical representation for this system is shown below. The common point is (160,240), this means that you spent $160 and your brothe spent $240.

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
