To solve such problems we must know about expressions.
Expression
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations that are formed according to rules which are dependent on the context.
The number of sandwiches bought can be given as [tex]\dfrac{x}{6.75}[/tex] where x is the total cost of all sandwiches.
Given to us
- A roast beef sandwich costs $6.75.
- A customer buys multiple sandwiches.
Assumption
Let the total Cost of all sandwiches be x.
Solution
Total Cost of all sandwiches
= Number of sandwiches bought x Price of each sandwich
[tex]x =Number\ of\ sandwiches \times \$6.75\\ Number\ of\ sandwiches =\dfrac{x}{6.75}[/tex]
Hence, the number of sandwiches bought can be given as [tex]\dfrac{x}{6.75}[/tex] where x is the total cost of all sandwiches.
