Cost of each shirt bought by Brain = 14.50
Then
Cost of 2 shirts bought by Brain = 2 * 14.50
= 29
Cost of a pair of shoes = 29.99
Total amount spent by Brain before tax = 29 + 29.99
= 58.99
Percentage of sales tax that needs to be paid = 6%
Amount of sales tax that needs to be [paid = (6/100) * 58.99
= 353.94/100
= 3.54
So
the total amount spent by Brain including tax = 58.99 + 3.54
= 62.53
I hope this is the answer you were looking for.
It would be x = 18
You can get this by adding/subtracting common values. If you get all the x values on one side and all constants on the other side, you end up with
2x = 36
and all you have to do is divide by 2 to get x = 18.
Primary grade children should not be rushed into working with fraction and decimal notation, [ because accordingly young children have a natural understanding and interest in parts and in wholes it can be used later as a bridge in learning fraction and other ways of breaking up whole numbers.
