Drew's weekly allowance is $8, and he spends $3 a week. Jan's weekly allowance is $10, and she spends $4 a week.
The video game Drew and Jan want to buy costs $55.
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.
Answer (2)
To find out how many weeks it will take them to save enough to buy the video game, we need to determine how much money they save per week. Drew spends $3 out of his $8 allowance, so he saves $8 - $3 = $5 per week. Similarly, Jan saves $10 - $4 = $6 per week. Now we can write an expression to represent the number of weeks it will take them to save enough. Let's use the variable 'w' to represent the number of weeks:
(5w) + (6w) >= 55
We want to find the value of 'w' that satisfies this inequality. This represents the number of weeks it will take them to save enough to buy the video game.
Drew saves $5 weekly while Jan saves $6 weekly, totaling $11 of savings each week. To buy a video game costing $55, they will need 5 weeks to save enough. The expression representing their savings over time is ( 5 w ) + ( 6 w ) ≥ 55 .
