Sales tax charged = $1.60
Sales tax rate =2.5%
Sales tax charged in terms of
will be = 2.5% of the Original price of grocery =
So, we have,

Dividing both sides by 

∴ 
∴ Price of Caleb's groceries before tax = $64
Assuming you means 6.5% tax of a $42 purchase
0.065*42=2.73
tax is $2.73
Answer:
see the explanation
Step-by-step explanation:
we have

This is the equation of a line in point slope form
where
the point is (-2,4)
the slope is m=1/3
Remember that the formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)
so
To graph the line
1. Plot the point (–2,4).
2. From that point, count left 3 units and down 1 unit and plot a second point.
3. Draw a line through the two points
Answer:
100% true....
subtracting 19 from both sides brings you to 2x=8, so x=4
Step-by-step explanation:
The answer is 32, depending on how you do the math will be different outcomes
