If I=P*r*t, we can input 450 in for I, 3000 in for the principal (P, or the starting rate), and 3 for t=time because there were three years, resulting in 450=9000*r. Next, we can divide both sides by 9000 to get 0.05 or 5% as our answer.
The answer is 14 hope this helps
Well in order to round 9.42 to the closest whole number we must know that. anything below 5 we round down and 5 and up we round up
So 9.42 becomes 9
of if your wanting to round to the nearest tenth it would be 9.4 you drop the 2 because you rounded down since it was lower than 5.
The decimal is .73 for this question.
Answer:
1 taco costs $1.5 and 1 burrito costs $3.25
Step-by-step explanation:
-Let t denote tacos and b denote burritos.
-The system of equations in the two weeks can then be expressed as below:
make t the subject of the formula in i and then substitute in ii to solve for both unknowns:
Hence, 1 taco costs $1.5 and 1 burrito costs $3.25
