Answer:
Step-by-step explanation:
Cost price = $n
Mark up price = selling price- cost price
= (20% × $n)
Selling price = $n + (20% × $n)
Sales tax = 5% × ($n + (20% × $n))
Total cost = selling price + sales tax
Total cost = $n + (20% × $n) + 5% × $n + (20% × $n)
= 1.2 × $n + 0.06 × $n
= 1.26 × $n.
Answer:
<em>y ≥ - 0.8 </em>
Step-by-step explanation:
= 5y + 4
= 5y + 4
5y + 4 = 5y + 4 and 5y + 4 ≥ 0 ⇒ y ≥ - 0.8
y ∈ [ - 0.8 , ∞ )
- ( 5y + 4 ) = 5y + 4
10y = - 8
y = - 0.8
The answer is <em>y ≥ - 0.8</em>
