Suppose you spent $74.95 for a shirt and a jacket. The shirt cost $20.25. Solve the equation 20.25+j=74.95 to find how much you spent on the jacket. You can work a simpler problem to estimate an answer. Use number sense to solve 20+j=75

    They've given you the formula. You just need to solve for \(j\).

    If I told you 4 plus a number equals 9, how would you figure out what "the number" is? Tell me your process.

    20.25 plus a number(\(j\)) equals 74.95.

    when burned, 18 gallons of gasoline produce about 360 pounds of carbon dioxide. solve the equation 18n=360 to find how much carbon dioxide 1 gallon of gasoline produces.

    360 = 18x if you divide by 18 you would get 20 because if 10 x 18 = 180 then 20 x 18 would be double that and 180 x 2 = 360
