Question

Pizza cost $1.50 per slice. Use a table and an equation to represent the relationship between the number of slices of pizza bought and the total cost

Answer 1

`\left[\begin{array}{cc}Slices&Cost\\1&\$1.50\\2&\$3.00\\3&\$4.50\\4&\$6.00\\.&.\\.&.\end{array}\right]`

Let Cost=
`C` and Number of Slices=
`s`:

`C=1.50s`

Answer 2

`y = 1.5x`

Explanation:

Let the total number of slices one would purchase be
`x`

Cost of
`1` slice =
`\$1.5`

Let the total cost for
`x` slices be
`y`

∴ Total cost for
`x` slices will be given by the equation-

`y = 1.5x`

`\left[\begin{array}{ccc}Slice&Price\\1&\$1.5\\2&\$3\\3&\$4.5\\.&.\\.&.\end{array}\right]`
