Simon bought a $48 table on sale. The price of the table can be estumated by $50.

The sale propose 30% off, then an estimate for the discount can be calculated using proportion:

$50 -- 100%,

$x -- 30%

that is mathematically

\(\dfrac{\$50}{\$x}=\dfrac{100\%}{30\%}.\)

Find x:

\(\$x=\dfrac{\$50\cdot 30\%}{100\%}=0.3\cdot \$50.\)

Answer: correct choice is B

Answer:

b. \(0.3\cdot(50)\)

Step-by-step explanation:

We have been given that Simon bought a $48 table on sale at 30% off. We are asked to choose the correct option that gives an estimate for the discount .

Since 48 is very closer to 50, so to find an estimated amount of discount we need to find 30% of 50.

\(\text{Estimated amount of discount}=30\%\text{ of }50\)

\(\text{Estimated amount of discount}=\frac{30}{100}\cdot(50)\)

\(\text{Estimated amount of discount}=0.3\cdot(50)\)

Therefore, an estimate for the discount is \(0.3\cdot(50)\) and option 'b' is the correct choice.
