The dough for the world's largest pizza was baked in 5,234 batches. Suppose it took the chefs 3 hours to bake the first 327 batches, and they bake the rest of the batches at the same rate. How long would it take to bake all the batches? Explain your reasoning.
Answer:
3.9%
Step-by-step explanation:
The formula for compound interest to apply is;
where;
A=amount at the end
P=starting amount/principal
n=number of compounding years
t=total number of years
r=interest rate expressed as a decimal
Given
P=$4200, n=2, t=4 and A=$4900 R=?
Substitute values in equation, take r=r
Divide both sides by 4200
Introduce root 8 to the left hand side, thus eliminating the power 8 in the right hand side
r=3.9%
