The total amount of money that Jenny and Susan spent is the sum of the money spent for the games and pizza. That is,
T = $93 + $6 = $99
We let x be the amount that Susan has. With this representation, the amount of money that Jenny has is x + 17. The equation that would represent this situation is,
x + 17 + x = 99
The value of x from the equation is 42.
ANSWER: $42.
Answer:
1.989 divide -10.45 =.19033493
Step-by-step explanation:
y = a(1-r)^×
source: https://mathbitsnotebook.com/Algebra2/Exponential/EXGrowthDecay.html
y = exponential decay
a = initial amount = 78000
r = decay rate = .03
x = number of time intervals = w
Error:
b = growth/ decay factor
b = 1+r for growth
b = 1-r for decay
x = w per the above information
Sarah did not account for either of these points when creating her equation.
Correct solution:
y = 78000 (1-.03)^w
Answer:
520
Step-by-step explanation:
if you subtract 65 from 325, you get 260.
if you multiply 260(half the original price) you would end up with 520
