Question

Two friends went to a restaurant and ordered one plain pizza and two sodas. Their bill totaled $15.95. Later that day, five friends went to the same restaurant. They ordered three plain pizzas and each person had one soda. Their bill totaled $45.90. Write a system of equations that represents this situation.

Answer 1

Explanation:

Given

One plain pizza and two sodas cost $15.95

Similarly, 3 plain pizzas and 5 sodas cost $45.90

Suppose the cost of single pizza and soda be
`x` and
`y`

In linear equation format, it can be written as

`\Rightarrow x+2y=15.95\\\Rightarrow 3x+5y=45.90`

Therefore, the above two equations represents the given situation.
