Answer:the unit rate is $0.5
Step-by-step explanation:
Andre rents a bike for a day. The rental changes can be determined by the equation: R = $0.5d, where R is rental changes and d is number of days she rents the bike.
The unit rate multiplied by the number of days for which the bike was rented would give the total rental charge. From the given equation, the unit rate would be $0.5
45 + 4 makes 49 if that counts
Ella has 0.5 lbs of sugar. 75% syrup
Percent of mass = 
Let the mass of solution is x
Given mass of solute = 0.5
percent of mass = 75
75 = 
75x = 0.5 * 100
75 x = 50
x = 0.67
Mass of solution = 0.67
Mass of water = mass of solution - mass of solute (sugar)
= 0.67 - 0.5 = 0.17
So 0.17lb of water is added with 0.5lb of sugar to get 0.67lb of solution.
