We have been given that you went to Walmart and spend $75. Of the total bill, $45.50 included non-taxable items.
Let us find the amount of taxable items by subtracting amount of non-taxable items from total bill.


We have been given that the rate of tax is 7.5% to the taxable items. To find the amount of tax, we will find 7.5% of $29.50.


Final amount of bill would be amount of bill plus amount of tax.


Therefore, final amount of bill would be
.
There are two pints in a quart
so 3 times 2 equals 6
3 qt = 6 pt
Remember them is the best way to go.
draw the exact value triangles if you're unsure, but importantly, you just need to memorise these exact values.
Realize the tangent function has a period of 180°, so when your calculator (or memory) tells you
.. θ = arctan(-1)
.. θ = -45°
you can translate that value into the desired range by adding multiples of 180° to get the two solutions ...
.. θ = 135°
.. θ = 315°
