Answer:
$2.99
Step-by-step explanation:
Given that:
Purchase price of cat calendar = $1.30
Markup = 100%
Hence, price at which the cat calendar was sold :
1.30 + 100%(1.35)
$1.30 + $1.30 = $2.60
Sales tax = 15%
Amount paid as sales. tax _
15% * 2.60 = $0.39
Total amount paid :
$2.60 + 0.39 = $2.99
Kim's age is twice of that of her sister. We'll let k2 = Kim and k = Kim's sister.
So, k2. When you add Kim's age to her sister age you get 36.
Because Kim is twice the age of her sister k2. And because it said 'add' then we put a + sign. k2 + s = 36. Now let's solve it.
k2 + k = 36 < Given
3k = 36 < Combine like terms
k = 12 < Divide both sides by 3
We know Kim's sister is 12 y/o but what about Kim herself? Earlier we assigned Kim to k2. Substitute 12 for k and you get 12(2) = 24
Kim's sister is 12 y/o and Kim is 24 y/o
