The equation is $4 \times \left(x + 5\right) = 54$ 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 $4 \times \left(x + 5\right)$dollars, which totals$54.

Putting this together, we have

$4 \times \left(x + 5\right) = 54$

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

$4 x + 20 = 54$

Collect like terms (by subtracting 20 from each side)

$4 x = 34$

Divide each side by 4

$x = 8.5$
