4.4
4.40
Step-by-step explanation:
These two decimals above are equivalent to 4.400 because no matter the amount of zeroes, the numbers are the same. For example, 4.400 is also equivalent to 4.400000000000000000000000000000000. As long as the "4's" maintain the same place (ones place and tens place), the decimals will be congruent to one another.

The cost of one shirt is 12.50 and cost of one pair of jeans is 24.75
Step-by-step explanation:
Let,
Cost of one shirt = x
Cost of pair of jeans = y
According to given statement;
4x+3y=124.25 Eqn 1
3x+5y=161.25 Eqn 2
Multiplying Eqn 1 by 3

Multiplying Eqn 2 by 4

Subtracting Eqn 3 from Eqn 4

Dividing both sides by 11

Putting 24.75 in Eqn 1

Dividing both sides by 4

The cost of one shirt is 12.50 and cost of one pair of jeans is 24.75
