The variable 'a' represents how much Arthur saves. Because D'John saves $8 per week (7 days), he saves $56. Arthur saves four times more than D'John so $56*4 equals Arthur's total savings for the week; $224.
a=$8(7)*4
a=$56*4
a=$224
The expression would be: m + 0.15m and to know how much she paid I believe it would be 26.09 (rounded)
Hope it helped!

Step-by-step explanation:
There is a difference in the two questions, but the result is found the same way
line is in the form y = mx + b
where m is the slope and b is the y intercept.
Perpendicular lines have negative reciprocal slopes
The desired line from the picture has a slope of 5
Now we plug in the included point
2 = 5(1) + b
b = -3
y = 5x - 3
The desired line from the write up has a slope of 1
Now we plug in the included point
2 = (1) + b
b = 1
y = x + 1
