The map below shows the location of 3 houses where you had to do lawn work today. your truck gets 8 miles per gallon of gasoline, so you chose the shortest route from your house to the jobs and then back home, as shown below. if gas costs $1.52 per gallon, what was the total cost of the gas that you used today?

the answer is 3.80 cents

Step-by-step explanation:

The total cost of gas is $3.80

Step-by-step explanation:

There are many ways to solve this, I will show you, in my opinion, the easiest way.

The only information needed from the map is the amount of miles that were traveled. Let's add up all of the miles to get the total amount that was traveled today --> 7+3+4+6= 20 total miles.

Next, we must figure out how many gallons of gas we used. Since 8 miles is equal to 1 gallon of gas, we can determine this by dividing our miles by 8 ---> 20/8 = 2.5 gallons of gas.

Finally, we must determine how much money this gas will cost. Given that one gallon of gas is worth $1.52, we can find this by multiplying our total gas with the cost of gallon per gas ---> 2.5 x $1.52 = $3.80 total. This is the final answer!

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
