A staining solution bottle in a medical laboratory contains 30 ounces .A blood staining test requires 3/4 of solution a tissue staining test requires 1/2 oz of solution if for blood tests and five tissue tests are performed how many ounces of solution are left in the bottle

Answer:5 ounces of solution are left in the bottle.Step-by-step explanation:Volume of the staining solution, s = 30 ozVolume required for the blood staining test = [tex]\frac{3}{4}[/tex] of solution[tex]=\frac{3}{4}\times 30 = 22.5 oz[/tex]Volume required for blood tests = [tex]\frac{1}{2}oz=0.5 oz[/tex]Number of blood staining tests run = 1Volume of solution required in 1  blood staining test ,x= 22.5 oz × 1 = 22.5 ozNumber of blood test run = 5Volume of solution required in 5 blood test ,y= 0.5 oz × 5 = 2.5 ozVolume of staining solution left : s - x- y= 30 oz - 22.5 oz - 2.5 oz = 5 oz5 ounces of solution are left in the bottle.
