You buy dog biscuits at the bulk rate price of $2.25 per pound. the scale shows the weight of 25 biscuits. find the cost of 40 biscuits. explain how you found your answer

price of 40 biscuits = $2.7

Explanation:
The scale is shown in the attached image.
1- Based on the scale, 25 biscuits weigh 0.75 pounds
We can use cross multiplication to know the number of biscuits that weigh exactly one pound as follows:
25 biscuits ...........> 0.75 pounds
?? biscuits ..........> 1 pound
number of biscuits = (1*25) / 0.75 = 33.3334 biscuits

2- We know that the price of 1 pound of biscuits is $2.25. This means that the price of 33.334 biscuits is $2.25.
We can again use cross multiplication to know the price of 40 biscuits as follows:
33.3334 biscuits ...............> $2.25
40 biscuits .......................> ??
price = (40*2.25) / 33.3334 = $2.7

Hope this helps :)
