Julie wrote the rate $108 in 6 weeks as a unit rate.Find her mistake and correct it.
natima [27]
Well for starters that would be $108/6 weeks when a unit rate is anything over one. To put it as a unit rate (how many dollars per hours) you just divide $108 by 6 (since you would divide 6 by 6 to get) and the unit rate would end up being $18 per hour.

We have to determine the constant in the equation, which shows how Eric can calculate his profit ( y ). He sells each shirt for $4 and he has total expenses: $100 + $10 = $110. So the equation for profit is: y = 4 x - 100. In this equation y is dependent variable, x is independent variable, 4 is coefficient and - 100 is the constant. A constant is a number ( a quantity that does not vary ). Answer: D ) - 110<span>.</span>
