8 pounds of pears would cost 64.00 because 40/5=8.00-price per pear so 8 pounds x8= 64.00
Head because is 50 chance
3 Because 7 x 3 = 21 and 7 + 3 = 10
7 x w = 21 and 7 + w = 10
5 bags is cheaper because one bag is $3 and 5 bags for ten so to find the unit price the amount (10/ ) the amount of bags (5) so therefore 10/5= $2 which is smaller than the price of an individual bag
In this question, you are given multiple number names and asked to add it. To answer this question it would be easier to split the description into a different part like this:
1. "18 tens" mean 18 * 10= 180
2. "20 ones" mean 20 *1= 20
If you add them, then you will got : 180+20= 200
