Give four examples for rational numbers equivalent to:
(i) -5/7
(ii) 40/80

Step-by-step explanation:

(i) -5/7

Here, we can write in the form of p and q. where, p = -5 and q = 7

(ii) 40/80 = 1/2

Here, we can write in the form of p and q. where, p = 1 and q = 2

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
