Mary bought a pair of jean and a sweater. the pair of jeans cost $30 and the sweater cost $35 if sales tax is 7% how much did Mary spend in total for the jeans and sweater

Mary spent a total of $69.55.

The total cost without tax for the pair of jeans and sweater is $65.

30 + 35 = 65

Now, we just have add on the tax. Since the tax rate is 7%, we just need to multiply by 1.07 to find the amount with the tax included.

65 x 1.07 = 69.55

To find the total amount Mary spent after tax, you will calculate the price before tax and then find the amount after the tax has been included.

1. $30 + $35 = $65

2. $65 x 1.07 = $69.55 (We multiplied by 1.07, because 1 is the whole price and the 0.07 represents the part that is the tax).

Mary's total cost after tax was $69.55.
