Step-by-step explanation:

9. $\tt{\dfrac{20}{25}×100 }$

$\tt{\dfrac{20}{\cancel{25}}×\cancel{100} }$

$\tt{80\% }$

80% students passed in test.

10. $\tt{5\%=136\$ }$

$\tt{ 1\%=\dfrac{136}{5} }$ $

Total income=100% = $\tt{\dfrac{136}{5}×100 }$

$\tt{2720 }$ $

Total earning=2720$

Please help with 1 and 2

ZanzabumX [31]

Answer:

1. B. a=14, b=2

2. D. a=1, b=1.4

Step-by-step explanation:

The exponential growth function can be represented as

$y=a\cdot b^x,$

where b is the growth factor.

1. When the function has equation

$g(x)=14\cdot 2^x,$

then

$a=14,\\ \\b=2$

The initial amount is the value of the function at x=0:

$g(0)=14\cdot 2^0=14\cdot 1=14$

The growth factor is b=2

2. When the function has equation

$f(t)=1.4^t,$

then

$a=1,\\ \\b=1.4$

The initial amount is the value of the function at t=0:

$f(0)=1.4^0=1$

The growth factor is b=1.4

Answer:

$54.37

Step-by-step explanation:

First, need to find 15% of 47.28.

47.28 x .15 = 7.092

Then we add that to the original cost.

47.28+7.092 = 54.372

Round your answer

$54.37
