Matrix m shows the one-way fares for four commuter train routes. if the rail service raised fares by 12% on all routes and days, which formula shows how to find the matrix that would display the new fares? a) 0.12m b) m + 0.12 c) m + 0.12m d) 1 + 0.12m

C) M + 0.12M

Step-by-step explanation:

A — calculates the raise, not the new fare

B — adds 12¢ to every fare

C — adds 12% of the current fare to the current fare. This is what you want.

D — adds $1 to the amount of the raise. This is not the amount of the new fare.

C)

Step-by-step explanation:

Given : Matrix M shows the one-way fares for four commuter train routes.

If the rail service raised fares by 12% on all routes and days.

Then, the proportion of service raised fares on all routes and days. =0.12

Then, the new fares is given by :-

Hence, the formula shows how to find the matrix that would display the new fares =

the answer is 6

hope this !
