F=5.77X10^9(1.032^(y-1985)), we want to know when this is:

2.2X10^12=5.77X10^9(1.032^(y-1985))

381.2825=1.032^(y-1985)

ln(3,812825)=(y-1985)ln(1.032)

ln(3.812825)/ln(1.032)=y-1985

y=1985+ln(3.812825)/ln(1.032)

y≈2027.5

So GDP will reach 2.2 trillion during the year 2027.

four students spent $12 on school lunch .at this rate,find the amount 10 students would spend on the same school lunch

dimaraw [331]

In order to solve this, we need to figure out how much ONE student spends.
$\frac{12dollars}{4students} = 3$ dollars per student.

If 10 student spent for lunch, we just have to multiply our number by how much each student spends.
$10students* \frac{3dollars}{student} = 30dollars$
