Find two numbers, if their sum is −11 and their difference is 41

15 and -26

Step-by-step explanation:

the fist # = x

The 2nd # = y

equation:    x + y - 11 = -x + y - 41

                           + 11   +x  -y  +41  

                                  2x=30

                                     x=15

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
