What is the area of a triangle with a base of 15 1/4 inches and a height of 10 inches?

Area of the triangle is 76.25 in²

Step-by-step explanation:

Area of the triangle = 1/2 × base × height

                                 = 1/2 × 61/4 × 10 = 76.25 in²

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
