Step-by-step explanation:
Oh boy, well looking in perspective 47.50 per ton
there are 2.5 tons. Lets break this down:
2 and half tons
2 x 47.50= N
Noted after using our trusty calculator you'll get 95
2 x 47.50= 95
then you have that half
which would look like this : 2/47.50
Divide 47.50 by 2 (Because a half is .5 or 1/2 of the whole number in this case 47.50)
2/47.50 =23.75
Next add up your two new answers 23.75 + 95 = ?
Hope this helps.
