Question

a nursery worker buys 9 panes of glass. the 9 panda cost 26.55 unfortunately she breaks 4 more panes. what is the cost of another 4 panes of glass?

Answer 1

The cost of another 4 panes of glass is $10.2

Explanation:

An expression is a way of writing a statement with more than two variables or numbers with operations sucb as addition,subtraction,multiplication,and division.

Examples : 2+3x+4y=7 is an expression

we have and

cost of 9 panes = $22.95

cost of one pane = cost of 9 panes divided by number of panes

therefore,

=
`(22.95)/(9)`

= $2.55

now,

cost of 4 panes = number of panes required multiplied by cost of one pane,

hence,

= 4*2.55

= $10.2

Thus,

The cost of 4 panes is $10.2.
