Answer:
18 but look at others awnsers aswell
Step-by-step explanation:
29/9 kilograms because 7/3 is equivalent to 21/9 and then 21/9+8/9 = 29/9
It looks like it goes through (0,-3) and (1,2), so the gradient is (change in y)/(change in x) ->
(-3-2)/(0-1) = 5
So y=5x+b
Then as we know it passes the y axis at (0,-3) so b= -3
So we have y=5x-3
0.75 x 14 = 10.50
15 - 10.50 = 4.50
your answer is : Sharon will receive $4.50 change
