Question

Shirt cost $20 each and ties cost $12 each. Write an expression for the cost of s shirts and t ties

Answer 1

20s+12t= is your expression.

Answer 2

The cost of "s" shirts and "t" ties = $20s + $12t

Explanation:

Given:

Shirt cost = $20 each

Ties cost = $12 each.

The number of shirts represented by "s" and the number of ties represented by "t"

Cost = $20*the number of shirts + $12*the number of ties

so, the cost of "s" shirts and "t" ties = 20s + 12t

Example:

If we want to find the cost 2 shirts and 3 ties, we need to plug s = 2 and t= 2 in the above expression.

The cost of 2 shirts and 3 ties = 20*2 + 12*3

= 40 + 36

= $76

The cost of 2 shirts and 3 ties is $76.
