Max is correct when he says he saved 15% altogether
Let assume that each item costs $100
With a 10% discount, he would pay $90
With a 20% discount, he would pay $80
The total amount he bought the items with the discount = $90 + $80 = $170
Without the discount, he would have paid = $100 + $100 = $200
Amount saved = $200 - $170 = $30
Percentage savings = x 100 = 15%
Max saved 15% in total

Answer:
<em>See the attached image</em>
Step-by-step explanation:
First, rearrange and simplify the equation:
16x – 4y = 28
–4y = –16x + 28
y = 4x – 7
Then, locate some points along the line:
f(0) = 4(0) – 7 = 0 – 7 = –7 → (0, –7)
f(1) = 4(1) – 7 = 4 – 7 = –3 → (1, –3)
f(2) = 4(2) – 7 = 8 – 7 = 1 → (2, 1)
f(3) = 4(3) – 7 = 12 – 7 = 5 → (3, 5)
Finally, draw a line across the points.
