Its an exponential function. The equation is
Y=950(1-0.025)^6
Most fool-proof way to do this in my opinion is to simply expand everything and write it out, i.e.
Throwing this into a calculator, we get
23.032To the nearest cent, this gives us
$23.03
Answer:
After 10 weeks, Susan will have $295 and CiCi will have $259.
Step-by-step explanation:
Susan: y= 65+23x
CiCi: y = 119+14x
65+23(6)=203
119+14(6)=203
After 6 weeks, Susan and CiCi will both have $203 in their accounts.
65+23(10)=295
119+(14)(10)=259
Therefore, After 10 weeks, Susan will have $295 and CiCi will have $259.
To calculate percentage increase. Subtract old and new value. Then divide answer by old value then multiply by 100:
289 -242 = 47
47÷ 242 × 100 = 19.4% (rounded to 2 s.f)
Answer:
w= -52
Step-by-step explanation:
We simplify the equation to the form, which is simple to understand
15-w/4=28
Simplifying:
15-0.25w=28
We move all terms containing w to the left and all other terms to the right.
-0.25w=+28-15
We simplify left and right side of the equation.
-0.25w=+13
We divide both sides of the equation by -0.25 to get w.
w= -52
Hope it Helps :) !!
