Lesson 18: representing situations with
inequalities
cool down: grape constraints
han has a budget of $25 to buy grapes. write inequalities to represent the number of
pounds of grapes that han could buy in each situation
1. grapes cost $1.99 per pound.
2 grapes cost $2.49 per pound.
3. grapes cost $c per pound

If grapes cost $1.99, the inequality would be 25 / 1.99 = X, if grapes cost $2.49, the inequality would be 25 / 2.49 = X, and if grapes cost $c, the inequality would be 25 / C = X.

Given that Han has a budget of $ 25 to buy grapes, to determine the number of pounds of grapes that Han could buy if 1) grapes cost $ 1.99 per pound; 2) grapes cost $ 2.49 per pound; and 3) grapes cost $ c per pound, the following inequalities must be raised:

1)

2)

3)

25 / C = X

1. 1.99x ≤ 25

2. 2.49x ≤ 25

3. cx ≤ 25

Step-by-step explanation:

1. The budget of Han to buy Grape is $25.

Now, if he buys x pounds of grapes at the rate of $1.99 per pound, then the inequality that represents the number of pounds of grapes that Han can buy will be given by  

1.99x ≤ 25 (Answer)

2. The budget of Han to buy Grape is $25.

Now, if he buys x pounds of grapes at the rate of $2.49 per pound, then the inequality that represents the number of pounds of grapes that Han can buy will be given by  

2.49x ≤ 25 (Answer)

3. The budget of Han to buy Grape is $25.

Now, if he buys x pounds of grapes at the rate of $c per pound, then the inequality that represents the number of pounds of grapes that Han can buy will be given by  

cx ≤ 25 (Answer)

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
