Solve the system by substitution y=x^2-2x+1 y=2x+1

 The required solution of the given system is

Step-by-step explanation:  We are given to solve the following system of equations by the method of substitution :

Substituting the value of y from equation (ii) in equation (i), we get

When x = 0, then from equation (ii), we get

When x = 4, then from equation (ii), we get

Thus, the required solution of the given system is

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
