Roland is purchasing Pottery supplies for his pottery class. He buys a portable pottery wheel for $382.00,modeling clay for $12.00, and a pottery tool set for $16.14. If the tax rate is 8.25%, find the total tax he paid. Then find the total cost of his purchase. ( Just so you know this is 7th grade math )♡♡

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
