This is the kind of problem that strikes fear into every student's heart so I want you guys to take a deep breath and know that we can do the word problems. One way you guys might have learned in your previous Math courses is to make a guess and check chart and just kind of like plug in values and see how that goes.
Okay a total bill for 3 hats and $2.50 tax is $44.50. The great thing about Algebra though is that you can get it correct the first time.
If you're not sure go ahead and do out this long division where I find out that they are $14 per each hat.
Also make sure that you put units on your answer, units meaning the dollar sign.
Since an equation is two expressions that are equal to each other, this means that what is done to one side of the equation has to be done to the other side as well so that the equation stays balanced.
Water Research Paper - Solving Two Step Equation Word Problems
In a two-step equation, work in the reverse order of PEMDAS.Next, solve the equation using inverse operations to isolate the variable.Remember that solving an equation and finding the value of the variable requires "undoing" what has been done to the variable.But be careful - sometimes word problems have two steps.Two-step math word problems require you to solve two equations (or number sentences) before you come to an answer. Look at the important information in the problem, and turn that information into an equation by translating the words into operations.It's like a shortcut when you can do an equation. Okay the total bill for 3 hats and 2.50 tax, I'm going to write that like this, 3 hats, h for hats and then I also have to pay 2.50 tax and I know that the total bill is .50. I'm accounting for those 3 hats plus the .50 tax.This is an equation that when I solve for h, I'm going to know how much each hat costs so it's pretty cool. In order to get h by itself I need to undo all this business so I'll subtract 2.50 from both sides, that's the opposite of adding so I'll have 3h, that's all that's left on that side, is going to be equal to right? So now I know that 3 hats cost , the last thing I want to do is divide both sides by 3 to find out that each hat is equal to whatever 42/3 is.The problem might have two different operations (like multiplication and addition), or it might have two of the same operation, like this one that requires subtraction twice: Begin your two-step word problem like you would any other word problem by reading it carefully to decide what you need to do, including which step to complete first. Feel free to draw pictures to help you through the problem.Let's try this on our two-step example word problem: Jacob gave Julia 1 sticker.The word problem is asking how many are left after you ate 3.So, you need to take Mom's total (36) and subtract (or take away) 3.
