Find the volume of the prism below.

here

height of the prism ( H )= 6m

area of a triangle ( A )= 1/2 × base × height

= 1/2 × 3 × 4

= 6 m^2

we know ,

volume of prism = H×A

= 6m × 6m^2

= 36 m^3

therefore volume of the prism is 36 m^3

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
