Mike and his family drove 460 miles on their vacation. Their car averaged 23 miles per gallon of fuel. If the cost of fuel was $1.55 a gallon, how much did they spend on fuel?

31 dollars

Step-by-step explanation:

460 miles in total ÷ 23 miles per gallon of fuel = 20 gallons

20 gallons x $1.55 a gallon = $31 dollars

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
