Francis heard that a car stereo system was on sale
for 30% off. If the sale
price was $57.75, what was
the original price of the
stereo?
(needs proportion, work and solution)

$82.5

Step-by-step explanation:

$82.5

Step-by-step explanation:

We can calculate it with a direct rule of 3. As it has a 30% off, the remaining price is the 70% and we want to know how much is the 100%

We use the formula of the direct rule of 3

x = 82.5

The original price of the stereo was $82.5

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.
