Answer:
2 notebooks
Step-by-step explanation:
I understand you already figured out that it was 3 notebooks, but when I calculated it, I believe he could only buy 2...
Personally, I would show my work by first doing the calculation: 2.75[1 notebook price]+ (3[pens/pencils per notebook]*1.10[pen/pencil cost])= $9.075 per notebook and 3 pens
If you then showed that you multiplied 9.075 by 2... you would get $18.15 which is the closest you could get to his limit of $22 without going over
If we applied your answer of 3 notebooks, then the total would be $27.225 which goes over the money limit.
Hope I helped!
Answer:
17. 2.75
18. 5.50
19. 8.24
Step-by-step explanation:
To find a tip, multiply the total by the percent as a decimal.
27.48*0.10 = 2.75
27.48 *0.20 = 5.50
27.48 = 8.24
Step 1-Distributive Property
8c-72=12c-2-4c
Step 2-Combine Like Terms
8c-72=8c-2
Step 3-Divide both 8c's by 8
-72=-2 -72 does NOT equal -2 so this equation has no solution...Hope this helps have a great Day!!!
