Hal is asked to write an exponential function to represent the value of a $10,000 investment decreasing at 2% annually. What mul
Alex_Xolod [135]

Answer:

0.98

Step-by-step explanation:

Explanation

The investment of $10,000 decreases by 2% every year. So the following year is usually (100 - 2)=98% of the previous year. This is a geometric progression.

In this case the first term = 10000

The second term = 98% × 10000 = 9800.

The common ratio = 9800/10000=49/50

The multiplicative rate of change that should be in Hal’s function = 49/50=0.98.

The equation of the exponential rate would be;

10,000ₓ0.98ⁿ.

where n is the number years.

Please help- A bakery sells cakes for $18 each and pies for $15 each. Last weekend the bakery sold 118 total items and earned $1
Sati [7]

Answer:

64 pies sold

Step-by-step explanation:

x = number of cakes sold

y = number of pies sold

Last weekend the bakery sold 118 total items

x + y = 118

Last weekend the bakery earned $1,932.

18x + 15y = 1,932.

Get rid of one of the terms, in this case x.

x + y = 118 becomes

18x + 18y = 2124

Subtract the equations from each other

(18x - 18x) + (18y - 15y) = 2124 - 1932

3y = 192

y = 64

Subsititue y into the orginal qeuation to solve for x and check it's right.

x + 64 = 118

x = 118 - 64 = 54

18(54) + 15(64) = 1932
