would like to pannaurchase a new bike that costs $205. she already has $34 saved. if she saves a. maximum of $12 a week, the following inequality can be used to find the minimum number of weeks, w, it will take anna to save the money to purchase the bike. 12w+34>205
To find the minimum number of weeks it will take Anna to save enough money to purchase the bike, we can solve the inequality:
12w + 34 > 205
Subtract 34 from both sides of the inequality:
12w > 205 - 34
12w > 171
Then, divide both sides by 12 to solve for w:
w > 171/12
w > 14.25
Since the number of weeks must be a whole number, the minimum number of weeks Anna will need to save enough money to purchase the bike is 15 weeks.
To find the minimum number of weeks it will take Anna to save enough money to purchase the bike, we can solve the inequality:
12w + 34 > 205
First, let's isolate the variable 'w' by subtracting 34 from both sides of the inequality:
12w > 205 - 34
12w > 171
Next, divide both sides of the inequality by 12 to solve for 'w':
w > 171/12
w > 14.25
Since 'w' represents the number of weeks and we cannot have a fraction of a week, we need to round up the value of 'w' to the nearest whole number:
w > 15
Therefore, it will take Anna a minimum of 15 weeks to save enough money to purchase the bike.
