The exponential function is defined as y = a(1+r)^x, where "a" represents the original account and "r" the rate of growth or decay.
Then we have the following:
1) 22% grow
y = a( 1 + 22%/100 )^x = a(1.22)^x
So the solution is: 124(1.22)^x
2) 12% decay
y = a( 1 - 12%/100 )^x = a(0.88)^x
So the solution is: y = f(x) = 44(0.88)^x
3) 20% decay
y = a( 1 - 20%/100 )^x = a(0.8)^x
So the solution is: f(x) = 22(0.8)
4) 12% Groth
y = a( 1 + 12%/100 )^x = a(1.12)^x
So the solution is: f(x) = 42(1.12)^x
Answer:
0.0278
Step-by-step explanation:
(1/6)(1/6) = 1/36 = 0.0278
Answer:
$64
Step-by-step explanation:
Since there were 4 of them and the coupons were $10 off, they saved a total of $40
To find how much they would have spent without the coupons, add 40 to 216:
216 + 40
= 256
To find the normal cost of one ticket, divide this by 4:
256/4
= 64
So, the price of one concert ticket without the coupon is $64
Answer:
260 gallons of lemonade
Step-by-step explanation:
Step one:
given data
We are told that Jada made 316 gallons of lemonade.
and later served 56gallons of the lemonade
Required
The remaining Lemonade
Step two
We have the total lemonade as 316
and the deducted as 56
the balance will be
= 316-56
=260 gallons of lemonade
Substitute 5 for g so...
5 times 11 =55
