For each situation, write an expression answering the question. The expression should only use multiplication,
a. A person's salary is $2,500 per month. She receives a 10% raise. What is her new salary,

The expressions for each statement are as follows:

a: 2500+(0.10*2500)

c: 250 + (0.075*250)

Step-by-step explanation:

Part a:

The required expression is:

Hence,

The expressions for each statement are as follows:

a: 2500+(0.10*2500)

b: 40 * 0.85

c: 250 + (0.075*250)

there are no figures how am i supposed to answer this question

step-by-step explanation:
