A stereo that normally sells for $125 is on sale for $90. By what percent has the price of the stereo been reduced?
omeli [17]
28%
so you subtract $90 from $125 and that gives you $35, then you must determine the percentage by trial to see what percent that $35 is of $125, you can tell by looking that it will be near to a third or 33%, but not quite that much, so work backwards from there and try 30% and because that is just a bit more that $35, reduce and try a smaller percentage, 28% of 125 is exactly $35

. Isabella buys a 1.75 litre carton of apple juice. What is the largest number of 200 millilitre glasses that she can have from
Free_Kalibri [48]

Answer:

<em>The largest number of glasses of juice Isabella can have from the carton is 8.</em>

Step-by-step explanation:

<u>Ratios</u>

Knowing the total capacity of the carton of apple juice Ct, and the capacity of each glass Co, we can calculate how many glasses can be taken from the carton by finding the ratio:

\displaystyle n=\frac{Ct}{Co}

There are 1,000 milliliters in one liter, thus the carton has a capacity of

C t= 1.75*1,000 = 1,750 milliliters

Thus,

\displaystyle n=\frac{1,750}{200}

n=8.75

Since we cannot have 8.75 glasses, we round to the previous integer, then:

The largest number of glasses of juice Isabella can have from the carton is 8.
