Answer:
He could multiply the amount one box ways by 100, or 0.6*100.
Step-by-step explanation:
It’s the second option- no the triangles are not similar
So y=-2+3 means y=3-2
y=1
so then subsitute 1 for y and solve
1=1/3x-1
add 1 to both sides
2=1/3x
multiply boht sides by 3
6=x
so x=6
y=1
$68 is discounted from the regular price.
To find this, you first divide 80% by 100 to get 0.8 (the decimal form of the percentage). Then, simply multiply 0.8 by 85 (or vise verse) to get $68. Since the question is asking for how much is discounted from the regular price, the final answer would be $68.
I hope this helps!
