What did you do with the numbers I gave you before like the 8 and the 10 to get me the answers?

Didn't you take my number and multiply by 8? Sorry I should have said like the 3 and the 10.
OpenStudy (anonymous):
8 calculators at $3 each costs 8 x 3 = $24
8 calculators at $10 each costs 8 x 10 = $80
8 calculators at $7 each costs 8 x 7 = $56
SO.....
8 calculators at $d each costs 8 x d = $8d

thats what i put when i wrote down the problem on here
OpenStudy (anonymous):
I think it says 8/d on your question. it isn't 8/d it is 8d which means 8 times d
OpenStudy (anonymous):
8D. Since one calc is D dollars, 8 calculators is 8 * D= 8D.
