(d) 0, 3.33, 6.67, 10, 13.33, 16.67.

Step-by-step explanation:

Part a.

From the given number line it is clear that

2 units = 20

So, length of 1 unit is

Therefore, the numbers on the number line are 0, 10, 20, 30, 40, 50.

Part b.

From the given number line it is clear that

4 units = 32.4

So, length of 1 unit is

Therefore, the numbers on the number line are 0, 8.1, 16.2, 24.3, 32.4, 40.5

.

Part c.

From the given number line it is clear that

4 units = 8.8

So, length of 1 unit is

Therefore, the numbers on the number line are 0, 2.2, 4.4, 6.6, 8.8, 11.

Part d.

From the given number line it is clear that

3 units = 10

So, length of 1 unit is

Therefore, the numbers on the number line are 0, 3.33, 6.67, 10, 13.33, 16.67.

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
