What can you do when the unit prices for two comparable items are listed using different units of measure?
a. The secondary units don't affect the cost. As long as both prices are in dollars or cents, you can
compare the two.
b. The unit prices are based on the cost of the whole package, so divide each base cost by each unit
price to get comparable units.
c. Use conversion rates to change one unit into the other unit, so that both prices are listed using like
units.
d. Unit prices are ratios, so you can add the two prices together and divide by the smaller unit price
to get a usable number.

C. use conversion rates to change one unit into the other unit so that both prices are listed using like units

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
