edward washed several cars to earn money for a set of beats by dr. dre. After he paid $43 for supplies, he had $198 leftover to pay toward his new beats. write and solve an equation to find how much money edward earned washing cars

So here we have Edward, working to get some Beats by Dre!

The numbers they give us can definitely be used to figure out how much he had before spending $43 on cleaning supplies.

Since we know that AFTER spending $43 on cleaning supplies he has $198, we will ADD $43 to $198.

198

+ 43

= 241.

After doing the math, we find out that he had $241 to start out with.

Now; to make an equation!

leftover + supplies = total.

The amount he had after spending money on supplies plus the amount he had already spent on supplies equals the total amount he made from washing cars - in this case, $241.

Let's take another similar scenario!

Edward is washing cars and, after spending $75 on supplies, has $175 left over to buy his Beats.

We'll go back to that equation we used earlier (leftover + supplies = total).

leftover ($175) + supplies ($75) = total ($250).

See? Using that equation and the numbers I gave, we calculated how much money he made overall.
