Final answer:

Danielle's expression doesn't provide the correct time frame for saving unless $385 is her savings rate. She needs to divide the cost of the television by her regular savings amount to find the needed time to save.

Step-by-step explanation:

Danielle is trying to figure out how long it will take to save enough money to buy a flat screen television that costs $510. However, her expression 510 ÷ (35×11) will not accurately give her the information she needs unless $385 (which is 35×11) represents her monthly savings or some other specific saving interval. To determine how long it will take to save the money, Danielle would need to know her savings rate per week, month, or another interval of time and then divide the total cost of the television by that rate.

For example, if Danielle can save $50 each month, the correct expression would be $510 ÷ $50/month. This would yield 10.2 months, assuming she can save that amount consistently every month without any additional costs or interest. Budgeting and cutting unnecessary expenses can also help Danielle accelerate her savings plan. If she finds ways to increase her savings rate by reducing discretionary spending, she would be able to purchase her desire faster.

Answer:

$510 is the amount she needs.

35*11 can reffer to a lot of things, let's suppose that she saves wins $35 and works 11 hours per day, so the amount would be equal to the amount of money that she wins per day.

Then the calculation

510/(35*11) would be equal to the amount of days that she needs to work to save the exact amount of 510 dollars, then this equation can help her.
