Answer:

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
