Answer:
$20
Step-by-step explanation:
3.25 + 1.50 + 0.125 per hundred and fifty dryers.
= 4.875 + 15.30 = 20.175= 20.18 rounded up to 2dp.
= $20
We half the dryers cost
Then quarter and manage the quarter in two additions to find 3/4 of 200
Alternatively, we get used to fractions fast and state in order
150 dryers = 75% of 200
0.75 x 6.50 = 4.875
150= $4.875
This way we can double check without calculator and make sense in our workings.
