2/5 = (2x2)/(5x2) = 4/10 = 0.4
Start with your $22.50 subtotal (cost without tax)
Then, solve for 6.5% of $22.50
Set your equation up like so: 6.5/100=x/22.50
Cross multiply then you should have 100x=146.25
Solve to get 1.4625% (If you need it rounded, it's 1.5%)
1.5% ----> $1.46
$22.50+$1.56=$23.96
She spent $23.96
Answer:
y=50x
Step-by-step explanation:
The dots rise up by 50 and go right by one. rise/run=slope
There is no y-intercept because the line intersects at the origin, (0,0)
So, the answer is y=50x.
