A boy bought an article for £9. He spent £4

Marina86 [1]

Answer:

Profit % = 39%

Step-by-step explanation:

Cost price of the article = 9

Price for repairing = 4

Therefore, Total cost of the article = 9 + 4 = 13

Selling price of the article = 18

Profit = 18 - 13 = 5

Hence,

$Profit \% = \frac{Profit}{Cost \ price} \times 100\\\\$

$= \frac{5}{13} \times 100\\\\=38.46 \%\\\\=38.5 \%$

Profit percent (to the nearest %) = 39%

Answer:

$b=\dfrac{1}{5}a$ .

Step-by-step explanation:

We need to write an equation for the amount of chemical B as a function of the amount of chemical A.

$b=f(a)$

$b\propto a$

$b=ka$ ...(1)

where, k is constant of proportionality.

It is given that fifteen grams of chemical A is used to produce 3 grams of chemical B. It means a=15 and b=3.

Substitute a=15 and b=3 in (1).

$3=k(15)$

$k=\dfrac{3}{15}=\dfrac{1}{5}$

Substitute $k=\dfrac{1}{5}$ in (1).

$b=\dfrac{1}{5}a$

Therefore, the required function is $b=\dfrac{1}{5}a$ .
