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) <u>></u> 80
=> 16 + 68 <u>> </u>80<u> </u>=> 80 <u>> </u>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
ABC and DEF are not similar transformations the second one is wrong, the third one is wrong because. The last one ios right because by deduction it is.
