Janice bought three lamps for her new apartment in a city where the sales tax rate is 5%. the lamps cost $25, $35, and $45. find the total cost of her lamp purchase , including sales tax.

Remark

You could do this by taking 5% of each lamp as

5% *25 + 25

5%* 35 + 35

5%*45 + 45

The easier way is to pretend that she bought all three at the same place at the same time.

(25 + 35 + 45)*(5/100) + 105

Easier yet is to do it this way.

(35 + 25 + 45)*1.05 = 105 * 1.05 = 110.25

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total

i think asking google will you get the answer to that question
