Dave bought a new game for $28. The tax rate was 7% How much was the tax and total price (if you can please add work I’m severel
LekaFEV [45]
Okay, let's find out how much the tax was by finding out what 7% of $28 is, we do this by multiplying:

\sf 28\cdot 7\%

Convert 7% into a decimal, we do this by dividing it by 100 because percentages are parts of 100:

\sf 28\cdot 0.07

Multiply:

\sf 1.96

So this is the tax. Add it to the original price to get the total price:

\sf 28+1.96=\boxed{\sf \$ 29.96}

Answer:

A=63.6 approximately

Step-by-step explanation:

P=14.28

p=1/4(2pi*r)

p=1/2pi*r

14.28=1/2pi*r

28.56=3.14*r

r=9...... approximately

A=1/4pi*r^2

A=0.25*3.14*81

A=63.6......approximately
