Answer :

The question contains a typo and should phrase 'for the dress as Susie' correctly. The number '90' is used correctly according to English writing convention for numbers 10 and higher, but the preposition 'as' seems out of place, requiring more context for complete correction.

Based on the context provided, it seems there is a typographical error in the question. The correct phrasing should likely be "
$90 for the dress as Susie"). When writing numbers in a sentence, numerical figures should be used for numbers 10 and higher. It is correct to use '$90' instead of spelling out 'ninety dollars' for the price of the dress. Additionally, names should be capitalized, so 'Susie' is correct. However, the preposition 'as' may be a typo or incorrect word choice, so further context is needed to correct the sentence fully. In summary, the number usage in the given context is correct, but there may be other grammatical errors present.
