Answer:
Step-by-step explanation:
Leaving aside that we don't know how much the carton weighs, the answer is 42 * 3.6 ounces (those are very big erasers).
W(carton) = 42*3.6 = 151.2
If x = 8, then the factor is (x - 8); likewise, if x = -5, then the factor is (x + 5). FOIL those together and get B
To find this, multiply 9.2 by the decimal form of the percent (4.75). The answer is 43.7
3 red shells equals $2.25 and 5 white shells equal 2.45. Add those together and you get $4.70.
So 3 red and 5 white shells would be the next guess.
