Answer: 28
the cost of 7 diaries is 28
Step-by-step explanation:
First you have to find out the cost of one diary by dividing 12 by 3, that will give us 4, and then the last step is multiplying 4 by 7.
128$ is the new sale price...
320 x .60 = 192....
now minus that with the normal price ..
310 - 192 = 128$
