Multiply the numbers being added then add the first number. 4X1=4, 4+1=5.
2X5=10, 10+2=12. 11X8=88, 88+8=96. I'm not sure how to get 40, though. 
Hope I could help.

A group of college students are going to a lake house for the weekend and plan on renting small cars and large cars to make the
aleksandrvk [35]
<h2>PLEASE MARK ME AS BRAINLIEST</h2>

the number of small cars rented is 6.

The number of large cars rented is 8.

Step-by-step explanation:

Step 1 :

Each small car can hold = 5 people

Each large car can hold  = 8 people

Step 2 :

Number of small cars rented = x

Number of large cars rented = x + 2

Step 3 :

Altogether the total cars can hold 94 people.

Total people = 5 people (No. of small cars) + 8 people (No. of large cars)

               94 =  5 (x) + 8 (x+2)

               94 = 5x + 8x + 16

               78 = 13x

                  x = 78/13 = 6

∴ Number of small cars, x = 6 small cars

  Number of large cars, x+2 = 8 large cars.
