(7x - 4x) + (5 - 16)
3x - 11
Answer:
7
Step-by-step explanation:
45/9 = 5
12 - 7 = 5
1) Plug the numbers into the equation for a simple interest rate. The equation is I = Prt, where P is the initial amount, r is the interest rate, and t is the time in years. 2) You have to turn the time into years, so put it over 12 (the months in a year) to turn it into a fraction for the unit of years, and plug in the equation to get I = 1200*0.81*(9/12). 3) Multiply this equation out to get 729.00, this is the answer. Answer: $729.00 interest. **TAKE THIS WITH A GRAIN OF SALT, you wrote the interest as dollars, but in this equation I assumed you meant to write it was a percent. If you did make a mistake and the 81 interest is a percent, then the math in this equation is correct. If it is an amount of money, then don’t copy it because it would be incorrect.
The charging rate equation for the auto mechanic is C = 50 + 40h(50 for the initial fee and 40 times h for every hour). If he works 10 hours in one day we have to plug in 10 into the hours spot, h.
C = 50 + 40(10)
Now we solve for C
C = 50 + 400
C = 450
The auto mechanic charges $450 for 10 hours.
