Question

Christilla and her friends purchased tickets for the factory that costs $13 each and bottled water that costs $1.50 each. Write an algebraic expression for the total cost of their night out

Answer 1

An algebraic expression for the total cost of their night out is
`T=13x+1.5y`.

Explanation:

Given:

Cost of per person ticket to factory =
`\$13`

Cost of each bottled water =
`\$1.50`

we need to write an algebraic expression for the total cost of their night out

Solution:

Let the number of persons visiting the factory be 'x'.

Also Let the number of bottled water be 'y'.

Also Let the total cost be 'T".

So we can say that;

total cost is equal to Cost of per person ticket to factory multiplied by the number of persons visiting the factory plus Cost of each bottled water multiplied number of bottled water.

framing in equation form we get;

`T=13x+1.5y`

Hence an algebraic expression for the total cost of their night out is
`T=13x+1.5y`.
