Julia has $80. She wants to purchase a nail paint set for $16 ans earrings. She spends the rest of the money on earrings. Each pair of earrings cost $8. Write an inequality for the number of pairs of earrings she can purchase?

Julies has 80 dollars

=> She wants to purchase $16 nail paint set

and spent the rest of her money on earrings which costs 8 dollars.

Write and inequality:

Let E be the number of earing she bought.

=> 16 + 8E = 80

=> 8E = 80 - 16

=> 8E = 64

=> 8E / 8 = 64 / 8

=> E = 8

Let’s check our answer

=> 16 + 8 (8) > 80

=> 16 + 68 > 80

=> 80 > 80

So, after the nail set is bought, she will have 80-16 left, that is 64. If each pair of earrings costs 8 dollars, then she can buy 64/8 = 8: She can buy 8 pairs of earrings.

I don't see how you can make an "inequality" with this.

If the question is interpreted that she doesn't spend all her money, then we could say, if we must that if y=number of earrings she can buy then

y≤8
