Aparticular car gets fuel mileage of 48 mpg in the city and 12% more on the highway. what is the cars fuel mileage on the highway?

Since its more you add, and so you do 48+12% and you get 53.76

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
