a)1
b)2
c)3
d)4

Answer

b)2

Explanation

There are 3 bracelets to be chosen regrades of the order.

If this was the case, there would be 3! ways.

3! = 3 × 2 × 1

   = 6 ways.

But one of the bracelets is chosen first. So, there are only 2 bracelets left to be interchanged.

∴ 2! = 2 × 1

       = 2

Y X Z  and Y Z X

B

Step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
