Raymond went to the supermarket and bought a bar of chocolate for
three dollars and three cents. When he returned home, he found he
had four dollars and sixty-one cents left. Write an equation to find
how much money Raymond had before going to the supermarket, and then solve it.

Well first off, letโs define a variable called ๐ which represents
the amount of money in dollars that Raymond had before going to the supermarket. So he started off with ๐ dollars, he then spent three
dollars and three cents, and he was left with four dollars and
sixty-one cents.

So we can write that down. Weโve started off with ๐ dollars and
then we took away three point o three dollars, three dollars and
three cents. And that left us with four point six one dollars,
four dollars and sixty-one cents. So weโve done the first part of the question; we have written our equation. Now we need to go on and rearrange and solve that equation to find out how much
money Raymond had before he went to the supermarket.

Now I want to know what ๐ is. So if I add three point o
three to both sides of my equation, then on the left-hand side Iโve got ๐ minus three dollars and three cents
plus three dollars and three cents; these two numbers here are gonna cancel out, which just leaves me with ๐. And on the right hand side, Iโve got
four dollars and sixty-one plus three dollars and three, which is seven dollars and sixty-four cents.

So there we have our answer: Raymond had seven dollars and
sixty-four cents before going to the supermarket.
