Hayley has $155 in savings, and her brother Hank has $230. Hayley is saving $10 each week, and her brother is spending $15 each week. After how many weeks will their savings accounts have the same amount of money in them?
What is the best way to set up this word problem to solve?
15x+155=230+10x
15 x plus 155 is equal to 230 plus 10 x
155−15x=10x+230
155 minus 15 x is equal to 10 x plus 230
155+10x=230−15x
155 plus 10 x is equal to 230 minus 15 x
$155+$10x=$230-$15x is the correct answer because hayley currently has $155 in her saving and you have to add the 10 dollars she saves each week which is 10x. On the other hand, her brother has $230 and spends $15 dollars every week so that is 15x.
