Answer:By multiplying with (1+0.01x) where x is the percentage of increase, monthly pay rate of 21$ after marked up 78.7% and 10% profit will be $41.28.

Step-by-step explanation:

Given that pay rate is 21$ and it is marked up by 78.7% and made a 10% profit.

If any value marked up or made a profit of x% then we have to multiply with (1+0.01x) to find the new value.

New pay after 78.7% marked up using above formula is $21X(1+0.01X78.7)=21X1.787=37.527$

Now we have to use above formula again for 10% profit.

Hence new value $=37.527(1+0.01X10)=37.527X1.1=41.2797$ ≈$41.28

The cost for n students to attend a workshop is 7n+12 dollars. What is the cost,in dollars for students to attend?

You would divide both 12 and 7n by 7. To isolate the variable. You end up with 5+n. You can not say 5n because you cannot combine unlike terms. Your answer would be 5+n. Hope this helps
