Question

Ana decides to start a lemonade stand. She goes to the store to buy her supplies, and those cost her $50. The city of Richmond also requires anna to pay a fee of $5 per day to set up lemonade stand at the park. Write the equation for her total cost (c) in terms of (d) days.

Answer 1

`c=5d+50`

Explanation:

Given that:

Supplies of the lemonade bought at price = $50

Money paid per day to setup lemonade stand at the park = $5

To find:

Equation of her total cost.

Solution:

Let the number of days =
`d`

Per day cost of setting up the lemonade stand is given as $5.

If the number of days are
`d`, then the cost of
`d` days can be found by multiplying the per day cost with the number of days.

Therefore, the expression for cost for
`d` number of days =
`\$5d`

Total cost for
`d` number of days can be found by adding the cost of supplies and cost for
`d` number of days for setting up the stand:

`c=5d+50`
