Answer:
(a) Money spend on each pack will be $0.8
(b) Money send on each pack will be $0.2
Explanation:
We have given that Greg spent $4 on 5 packs of spot card
(a) We have to find how much Greg spend on each pack
Cost of each pack will be
![=(4)/(5)=$0.8](https://img.qammunity.org/2020/formulas/mathematics/middle-school/5bf6qj0dxsm7kl5j2w739gs8eroyf0kp9j.png)
(b) In this case it is said that Greg spent half of money
So money spent by Greg
![=(4)/(2)=$2](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ahqof60rckke3xtxbnzdhjxfkynx7kougi.png)
And he bought twice of pack than earlier
So number of packs he bought
![=5* 2=10](https://img.qammunity.org/2020/formulas/mathematics/middle-school/vnwaje7uu3w7ky2tj0s511fu312lse4bz9.png)
So money spend on each pack will be equal to
![=(2)/(10)=$0.2](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ulyxenmlt0fkn1emuhkvf0e1393p79t8ws.png)
