The paint costs $12.50 per gallon, and one gallon of paint covers 350 square feet! Reflecting tape costs $4.50 per roll of tape, and covers 40 linear feet.

Need a thorough explanation on parts A and B!

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)

If your asking how much altogether for 12 performance the answer will be 98,496.

The correct answer would be shape of function b = 2× slope of function a.
