Question

i really need help for this question.Please help me to solve this question with a clear explanation.

Answer 1

So, for four months, he averaged $82. That means he spent $82(4) = $328 total, right?

 

$90(4) = $360

$360 - $328 = $32

 

So, his total spending would have gone up by $32 if he spent $92 in January. He must have spent $92 - $32 = $60 in January.
