a. Write an inequality to represent this situation, where x is the number of stamps.

A)

7.65+49x≤10.00

B)

7.65−0.49x≤10.00

C)

7.65+0.49x>10.00

D)

7.65+0.49x≤10.00


b. Solve the inequality. What is the maximum number of stamps Keshila can purchase to mail letters?

x /≥? 4.7959/1.2431/0.0480?


Keshila can buy a maximum of 1/4/5/2? stamps.

The expression for the inequality is

D) 7.65+0.49x≤10.00

The number of stamps is x ≤ 4.795

Given Data

Let the number of stamps be x

Cost of mailing the package = $7.65

Amount that Keshila has = $10.00

cost per stamp = $0.49

We can use the equation of straight line to model the situation

y = mx +c

where y = the total amount that Keshila has

            x =  the number of stamps

            c = constant, the cost of mailing the package

Hence we have

7.65+0.49x≤10.00

Solving For x

0.49x ≤ 10-7.65

0.49x ≤ 2.35

divide both sides by 0.49

x ≤ 2.35/0.49

x ≤ 4.795
