# How to write an Algebraic expressions? This is my Question. Write the following orders as algebraic expressions. I'd like four hamburgers, six orders of French fries, a large soda, two medium sodas, and an extra large soda.

$4 h + 6 f + l + 2 m + x$

#### Explanation:

h=hamburgers
f=fries
l=large sodas
m=medium sodas
x=extra large sodas

$4 h + 6 f + l + 2 m + x$

$4 h + 6 f + 2 {S}_{M} + {S}_{L} + {S}_{E L}$

#### Explanation:

It is all about assigning meaningful letters to represent the unknowns. The question makes no stipulation which to use so you are free to select whatever you wish. One person would select one thing and somebody else another. What ever you decide on must be clearly declared.

I choose:

Let hamburgers be represented by $h$
Let French Fries be represented by $f$
Let medium soda be represented by ${S}_{M}$
Let large soda be represented by ${S}_{L}$
Let extra large soda be represented by ${S}_{E L}$

4 hamburgers $\to \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots . \text{ } 4 h$
6 French Fries $\to \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots . \text{ } 6 f$
1 large soda $\to \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots . . \text{ } {S}_{L}$
2 medium sodas $\to \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots . \text{ } 2 {S}_{M}$
1 extra large soda $\to \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots . \text{ } {S}_{E L}$

Mathematically putting together is +

So putting all these together we have:

$4 h + 6 f + 2 {S}_{M} + {S}_{L} + {S}_{E L}$
