<h3 />
How to find k using equation?
The value of k can be found as follows:
She bought two kids’ meals today for $7.30.
Yesterday, she bought three kids’ meals for $10.95.
Therefore,
p = km
where
m = number of meals bought
p = total cost of the kids’ meals
Therefore,
k = p / m
k = 10.95 / 3
k = 3.65

To find out the sales tax rate, we divide the sales tax by the cost of the item. This will give us what percent of the cost of the item the sales tax is equal to.
So, 20.4 divided by 340 = 0.06
To convert to percent, we multiply 0.06 by 100=6. Therefore, the sales tax rate is 6%.
Check:
340 times 0.06 (the sales tax rate) is 20.4 (the sales tax).
