Answer 1

Answer:

The expressions for each statement are as follows:

a: 2500+(0.10*2500)

b: 40 * 0.85

c: 250 + (0.075*250)

Step-by-step explanation:

Part a:

Given

Salary = $2500

Percentage of raise = 10%

The new salary will be:

$= 2500+ (10\%\ of\ 2500)\\=2500 + (0.10*2500)\\=2500+250\\=\ 2750$

Part b:

Given

Total questions = 40

Percentage of correct answers = 85%

The required expression for correct answers is:

$= 85\%\ of\ 40\\= 0.85*40\\=34$

Part c:

Given

Price of phone = $250

Percentage of sales tax = 7.5%

The required expression is:

$Cost\ with\ sales\ tax = 250 + (7.5\%\ of\ 250) \\= 250 + (0.075*250)\\=250+18.75\\=268.75$

Hence,

The expressions for each statement are as follows:

a: 2500+(0.10*2500)

b: 40 * 0.85

c: 250 + (0.075*250)
