The television cost $289.90. the sales-tax rate was 8%. how much was the sales tax on television.

You need to find what 8% of 289.9 is. To find this, multiply .08 by 289.9 = 23.192.
Because you are using money, round to the nearest hundredth and your tax is $23.19.
Hope that was helpful:)

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
