The sales tax on an item costing $236 is $28.20. What is the
sales tax rate to nearest tenth? Write ratio equation and solve it!
let the rate be i
i(236) = 28.2
i = 28.2/236
i = .11949
or 11.9%
Thank you Reiny
welcome!
To find the sales tax rate to the nearest tenth, we need to find the ratio of the sales tax amount to the cost of the item.
Let's represent the sales tax rate as a decimal, with "r" being the unknown rate. The sales tax amount is given as $28.20, and the cost of the item is $236.
The ratio equation can be written as:
r = 28.20 / 236
To solve for "r", we can divide the sales tax amount by the cost of the item:
r ≈ 0.1195
Now, to round the sales tax rate to the nearest tenth, we round the decimal to one decimal place:
r ≈ 0.1
So, the sales tax rate, to the nearest tenth, is 0.1 or 10%.
