$\huge{\fbox{\sf{n=5 }}}$

Step 1:

$⇒ {2}^{n - 5} \times {5}^{n - 4} = 5$

Step 2:

$⇒{2}^{n - 5} \times {5}^{n - 4} = {5}^{1} \times {2}^{0}$

On comparing values we get:

Taking:

${2}^{n - 5} = {2}^{0}$

Justin bought some yarn from his Favorite craft store. He can make one score for 3/5 of a ball of yarn. If he purchases 15 balls

Svet_ta [14]

Justin can make 25 scraves with 15 balls of yarn

<h3><u>Solution:</u></h3>

Given that Justin can make one scarve for 3/5 of a ball of yarn

He purchases 15 balls of yarn

<em><u>To find: number of scarves Justin can make</u></em>

Number of scarves Justin can make with 15 balls of yarn can be found out by dividing 15 balls of yarn by 3/5 of a ball of yarn

$\text {number of scarves }=\frac{\text { total yarn he has }}{\text { yarn needed for } 1 \text { scarve }}$

$\text {number of scarves }=\frac{15}{3 / 5}$

$\text {number of scarves }=\frac{15}{3} \times 5=25$

Thus he can make 25 scraves
