How old is Molly and your mom now? Assign a variable for the lowest test grade. We see that there are ounces of ingredient a in solution Y.

She had 84 prescriptions for the two types of drugs. One ounce of solution Y contains ingredients a and b in a ratio of 1: The answer makes sense and checks in our equation from Step 4. One ounce of solution X contains ingredients a and b in a ratio of 2: This amount does not change.

Think about others ways you might use inequalities in real world problems. If solution Z is made by mixing solutions X and Y in a ratio of 3: We know that answer is 50, so now we have an equation Step 5: An equation is written with an equal sign and an expression is without an equal sign.

In this problem, the variable was defined for you. Altogether they drove 90 miles. The lowest grade on an algebra test.
