A Starbucks coffee costs $4.50. What is the total price if the sales tax rate is 7%?

Mathematics
1 answer:

7 0

Multiply 4.50 by 0.07

4.50*0.07 = 0.315

Then the sales tax is about $0.32.

You can also do it mentally. Moving the decimal point in 4.50 once to the left gives you 10% of the original amount, 0.45. Move it again to get 1% of the price, 0.045. Then multiply this by 7 to get 7%.

In your lab, a substance's temperature has been observed to follow the function T()- (x- 2)3 +8. The turning point of the graph
Vlad1618 [11]

We have the function:

T(x)=(x-2)^3+8

A turning point happens when the function reaches a maximum or a minimum.

In that points the value of the first derivative of the function is equal to 0.

So we can find the turning points by finding the first derivative and equal to zero:

undefined
