Question

Tatiana wants to give friendship bracelets to her 32 classmates.

She already has 5 bracelets, and she can buy more bracelets in packages of 4.
Let p represent the number of packages.
Write an inequality to determine the number of packages Tatiana needs to buy.

What is the minimum whole number of packages Tatiana needs to buy?

Answer 1

Let p represent the number of packages

bracelets in packages of 4.

She already has 5 bracelets


so if she buys p packages,

total number of bracelets = 5 + 4p

setting up inequality

5 + 4p >= 32

4p >= 32 - 5 = 27

p >= 27/4

minimum whole no. is 4

Answer 2

Let p represent the number of packages.

Inequality: 4p + 5 ≥ 32


4p + 5 ≥ 32
4p ≥ 32 - 5
4p ≥ 27
p ≥ 27/4
p ≥ 6.75

Minimum number of whole packages to buy is 7
