Allie is saving to buy a phone she wants to have at least $299 saved for buying one she currently has $213 saved and she receives $10 a week as an allowance from her parents after how many weeks will Ellie have enough money saved Ellie writes the inequality 10 W +213 is greater than in quality 299 where W is the number of weeks to help figure this out, solve her inequality
To solve the inequality 10W + 213 > 299, we need to isolate the variable W.
First, subtract 213 from both sides of the inequality:
10W + 213 - 213 > 299 - 213
10W > 86
Next, divide both sides of the inequality by 10 to solve for W:
10W/10 > 86/10
W > 8.6
Since W represents the number of weeks, it cannot be a decimal. Therefore, Allie will need to save for at least 9 weeks to have enough money saved.
