Darla's weekly salary can be described as 120+0.15s where s represent her sales that week if she received $277.50 this week how much would a total sales

you have the equation, so just solve

120 + 0.15s = 277.50
0.15s = 157.50
s = 1050

"how much would a total sales"
is a rather strange way to ask the question.

To find the total sales, we need to rearrange the formula given for Darla's weekly salary:

Weekly Salary = 120 + 0.15s

Given that her salary for the week is $277.50, we can substitute this value into the formula and solve for s:

277.50 = 120 + 0.15s

Rearranging the equation to solve for s:

0.15s = 277.50 - 120

0.15s = 157.50

Dividing both sides by 0.15:

s = 157.50 / 0.15

s ≈ 1050

Therefore, the total sales for the week would be approximately $1050.

To find the total sales, we need to reverse the equation representing Darla's weekly salary.

The equation given states that Darla's salary is equal to $120 plus 0.15 times her sales for the week (represented by 's').

Let's rearrange the equation to solve for 's':

Salary = 120 + 0.15s

Given that Darla's salary for this week is $277.50, we can plug this into the equation and solve for 's':

277.50 = 120 + 0.15s

To isolate 's', we subtract 120 from both sides of the equation:

277.50 - 120 = 0.15s

157.50 = 0.15s

Now, to solve for 's', we divide both sides of the equation by 0.15:

157.50 / 0.15 = s

s ≈ 1050

Therefore, the total sales for the week would be approximately $1050.
