Respuesta :
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
[tex]\dfrac{\$50}{\$x}=\dfrac{100\%}{30\%}.[/tex]
Find x:
[tex]\$x=\dfrac{\$50\cdot 30\%}{100\%}=0.3\cdot \$50.[/tex]
Answer: correct choice is B
Answer:
b. [tex]0.3\cdot(50)[/tex]
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.
[tex]\text{Estimated amount of discount}=30\%\text{ of }50[/tex]
[tex]\text{Estimated amount of discount}=\frac{30}{100}\cdot(50)[/tex]
[tex]\text{Estimated amount of discount}=0.3\cdot(50)[/tex]
Therefore, an estimate for the discount is [tex]0.3\cdot(50)[/tex] and option 'b' is the correct choice.
