Madison was out at a restaurant for dinner when the bill came. She wanted to leave a tip of 13%. What number should she multiply the cost of the meal by to find the total
plus tip in one step?

0.13

Step-by-step explanation:

13% is equal to 0.13

1.13

Step-by-step explanation:

It is like a percentage increase. The original price is just 1, and the extra thirteen percent for the tip is like 0.13. You add them together. If there is a percentage decrease then you would subtract the percentage decrease by 1.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
