Substitute the values given
(2+1)^-9
(3)^-9
When the exponent is negative, because of the negative exponent rule, this value goes into the denominator, as 1/((3)^9). This would be quite small to write as a decimal, so in scientific notation it is written as 5.08e-5 or 1/19,683 as a fraction.
12+.60+ 12.60
12.60*20%
12.60*.20= 2.52
Tip should be around $2.52
