Answer:
a= 15
Step-by-step explanation:

3a = 45 ( divide both sides by 3 )
a = 15
£30
This is because if she has put 40% in to savings she has 60% left. This 60% is 15 + 3 (the money she spent at the movies and the money she has left) = £18
So 60% : £18
10% : £3 (divide by 6)
100% : £30 (multiply by 100)

Answer:
$41.69
Step-by-step explanation:
The computation of the selling price of the each pair of slacks is as follows:
Given that
Cost = $19.36 per pair
Markup = $22.33
As we know that
Markup = Sell Price - Cost
So,
Sell Price = Cost + Markup
= $19.36 + $22.33
= $41.69
Hence, the selling price is $41.69
