Question #b318a

Answer 1

The equation is `4xx(x+5)=54` and by solving, we get `x=8.5` meaning each salad costs $8.50

Explanation:

Let `x` be the cost of a salad. Then each day, she spends `x+5` dollars. After doing this for four days, she has spent `4xx(x+5)` dollars, which totals $54.

Putting this together, we have

`4xx(x+5)=54`

Now, to solve, multiply each term in the brackets by 4:

`4x+20 = 54`

Collect like terms (by subtracting 20 from each side)

`4x = 34`

Divide each side by 4

`x=8.5`

The salad costs $8.50
