Question

Drew's weekly allowance is $8.00. C. the video game that drew and Jan want to buy cost $5.5. Write an expression to show how many weeks it will take them to save enough to buy the video game. Use parentheses and brackets in your expression. Then evaluate the expression.His friend Jan's weekly allowance is $10.00. Drew spend $3 a week and Jan spend $4 a week.

Answer 1

You don't say whether "Drew spend $3/week" means $3/week on things other than the video game.  I will assume this is what you meant.

Jan's available $ to apply towards buying the game is $10-$4 = $6/week.
Drew's                                                                       is $8-$3    = $5/week

Seems that something's wrong here.  Together, Jan and Drew have $11 per week to spend on the game.  If the game is only $5.50. then Jan and Drew together can buy it after 1/2 a week.  But if you meant $55, then Jan and Drew together can buy it after ($55/$11), or 5, weeks.

Answer 2

Is that suppose to be 5.50
