Answer:

40.6 inches

Step-by-step explanation:

The plant's initial height is 7 inches tall.

It grows 1.3 inches each day for 27 days. This means that after 27 days, it must have grown an extra:

1.3 * 27 = 35.1 inches

It must have grown an extra 35.1 inches after 27 days. Therefore, its new height after 27 days is:

7 + 35.1 = 42.1 inches

The plant then begins falling over 0.5 inch for the next 3 days. After 3 days, it must have fallen over by a height:

0.5 * 3 = 1.5 inches

Therefore, after 30 days, the plant's new height is:

42.1 - 1.5 = 40.6 inches

The plant's height after 30 days is 40.6 inches

4x = $4.84
x = 4.84 / 4
x = 1.21
Thus, the cost of toy car is $1.21.
