Question

Lily bought 6 skirts and 5 coats for a total of $452.62. If Lily sister bought 3 skirts and 5 coats for $289.36, what was the price of the coat?

Answer 1

Answer:

Step-by-step explanation:

First find 1/A

1/a= rationalizing of factor root under 2+1= root under 2-1

Now find value of a-1/a=(root under 2+1)+(root under 2-1)×-1

=root under 2+1×-root under 2+1

=root under 2 and - root under 2 cancel

Now remain 1+1=2 ans

Answer 2

The price of each coat is $ 25.22

Solution:

Let the price of each skirt be "a"

Let the price of each coat be "b"

Lily bought 6 skirts and 5 coats for a total of $452.62

6a + 5b = 452.62 ------- eqn 1

Lily sister bought 3 skirts and 5 coats for $289.36

3a + 5b = 289.36 -------- eqn 2

Subtract eqn 2 from eqn 1

6a + 5b = 452.62

3a + 5b = 289.36

( - ) ----------------

3a = 163.26

a = 54.42

Substitute a = 54.42 in eqn 1

6(54.42) + 5b = 452.62

326.52 + 5b = 452.62

5b = 126.1

b = 25.22

Thus price of each coat is $ 25.22
