22.5 (shower) = X (variable used in place of the amount of water she uses to wash clothes) - 7.5 (the amount she used in the shower is 7.5 gallons less than she uses for washing clothes)
22.5 = X - 7.5 《 This is the equation.
Solve is by adding 7.5 to both sides to cancel out the negative 7.5 and you get (X = 30).

If all the cheese slices have same mass, say m grams

ANSWER
y = 100 + 0.25(160) - equation
y = 140 - if you needed the answer
<span>d. y = 15x 900</span>
Although you do not give the rates I assume the answer is D as it is the only positive multiplication. You cannot have negative height.
