Question

Fern knitted 20 scarves over 5 nights. After 8 nights of knitting, how many scarves would fern have made in total.

Answer 1

Answer:

Fern will knit 32 scarves in 8 nights.

Step-by-step explanation:

Number of scarves knitted by Fern in 5 night = 20

Relation between number of scarves knitted and number of nights is proportional,

Therefore, Number of scarves knitted (s) ∝ Number of nights spent to knit the scarves (n)

s ∝ n

s = kn

k = $\frac{s}{n}$

Here, k = proportionality constant

For s = 20 and n = 5,

k = $\frac{20}{5}$

k = 4 scarves per night

For 8 nights, by using the same proportionality rule,

k = $\frac{s}{8}$

4 = $\frac{s}{8}$

s = 32 scarves

Therefore, Fern will knit 32 scarves in 8 nights.
