Answer:
y = -x -3
Step-by-step explanation:
I went to Desmos and kept guessing y intercepts until the line passed through the point (-4, 1). Sorry I can't explain the real way to figure this out.
Aiden will receive $1.43 from a $5 bill.
If the state tax is 5.5%, you can use the equation below to solve for the total cost, <em>t</em>.
<em>t</em> = 1.055 (2 × 1.09 + 1.20)
<em>t</em> = 1.055 (2.18 + 1.20)
<em /><em>t </em>= 1.055 (3.38)
<em>t </em>= 3.5659
You can round 3.5659 to $3.57. Finally, you subtract 3.57 from 5 to find the amount of change Aiden will receive, <em>c</em><em />.
<em>c </em>= 5 - 3.57
<em>c </em>= 1.43
