-2(4a+4b)+5a>-35<br> Solve the inequality

Amiraneli [1.4K]

Step-by-step explanation:

-2 (4a + 4b) + 5a > -35

-8a -8b + 5a > -35

-3a -8b > -35

for a

-3a > -35 + 8b

a < -35 + 8b ÷ -3

a < 35 - 8b ÷ 3

for b

-3a - 8b > -35

-8b > -35 + 3a

b < -35 + 3a ÷ -8

b < 35 - 3a ÷ 8

the price of an item has increased 15% since last year. However l a person can buy the item for a 25%employee discount. The empl

Fiesta28 [93]

Let us assume last year the price of the item = $x.

After increase in price by 15% the new price = x + 15% of x = x+ 0.15x = 1.15x.

There is a 25% discount for employee.

25% of 1.15x = 0.25 × 1.15x = 0.2875 x.

Price after discount = 1.15x - 0.2875 x = 0.8625x.

The employee pays $172.50.

Therefore,

0.8625x = 172.50.

Dividing both sides by 0.08625.

$\frac{0.8625x }{ 0.8625} =\frac{172.50}{0.8625}$

<h3>x=200.</h3><h3>Therefore, last year the price was $200.</h3>
