The scale drawing of a playground is 4 cm wide and 6 cm long. The playground is 14 m wide. How long is it?

21m

Step-by-step explanation:

From the question, we are informed that the scale drawing of a playground is 4 cm wide and 6 cm long and that the playground is 14 m wide.

Let the length of the playground be represented by x. Therefore,

4/6 = 14/x

4 × x = 14 × 6

4x = 84

x = 84/4

x = 21

Therefore, the length is 21m

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
