The net of a box is made by cutting four squares from a piece of cardboard.
The cardboard is a rectangle with width x cm
and length (x + 10) cm
Each square has side length 5 cm
The area of the net is 1475 cm2
The equation X2 + ax + b = 0 can be formed.
Work out the value of a and the value of b.

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
