A bedroom measures 18 feet by 20 feet. Find the cost to carpet at $4 per square foot.

$1440

Step-by-step explanation:

First, you need to find the area by multiplying 18*20, which is 360. Multiply 360 by 4 to find the cost to carpet the whole floor: 360*4 = 1440

$1440

Step-by-step explanation:

18·20=360 ft²

360·$4=$1440

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
