Answer:

The algebraic equations are: 120 + 120 × d% = 120 + x and 120 + 120 × 25% = 150

Step-by-step explanation:

The given number is 120 that is first increased by d% and then increased by 25%. So there is two algebraic equation, in the first equation the given amount 120 will be increased by d% and in the second algebraic equation, the given amount 120 will be increased by 25 percent.

Let the amount by which the 120 is increased = “x”  in the case of the first equation.

120 + 120 × d% = 120 + x

Second algebraic equation.

120 + 120 × 25% = 150

Answer:

1.5d+150

Step-by-step explanation:

125 ( 1 + 0.01d)

its 125 since it increased by 25%. put 125 into the parenthasees and theres your answer.
