Question

Leena is saving to take a dance class that costs $250, So far, she has saved $180 and is saving $7 each week. How many weeks it will take her to have enough money for the dance class? Part A: Define the variable

Part B: Write and solve an equation
Part C; Interpret the solution

Answer 1

To determine how many weeks it will take Leena to have enough money for the dance class, we can set up the equation 7x + 180 = 250 and solve for x. The solution is x = 10, meaning it will take Leena 10 weeks to save enough money.

Step-by-step explanation:

To determine how many weeks it will take Leena to have enough money for the dance class, we need to set up an equation. Let x represent the number of weeks it will take.

Leena saves $7 per week, so the total amount she saves in x weeks is 7x. Adding her initial savings of $180 to the amount she saves in x weeks, we can set up the equation:

7x + 180 = 250. To solve for x, we will subtract 180 from both sides: 7x = 250 - 180 = 70.

Dividing both sides by 7, we find that x = 70/7 = 10.
