Question

how do you solve this equation pls i need help

Answer 1

If Tatiana already has 5 bracelets and can only buy packs of 4 bracelets, if she buys p packs she will have

$5+4p$

bracelets. In fact, the 5 represents the bracelets she already has, and then we add 4p bracelets, because she bought p packs with 4 bracelets each.

We need this number to be at least 32, so we want

$5+4p\geq 32$

To solve the inequality, we can subtract 5 from both sides:

$4p \geq 27$

And divide both sides by 4:

$p \geq \dfrac{27}{4}$

Since p has to be an integer, we pick the first integer to be greater than 27/4, which is 7.
