Need some :
customer a has to pay $60.80
the sales tax is 8.5% on the items purchased.
what is the amount of tax customer a pays?
what is the total customer a pays for the items purchased on tuesday?

If you make it a little more clear i can answer it

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)

The answer would be 484
