Meera has been visiting banks all day trying to find the best compound interest rate for her savings account. The banks have decided that instead of telling her their rate, they are going to give her the equation that will calculate her current balance after t years. Below are the equations each bank gave to Meera, where f(t) is the balance after t years and P is the principal amount to be placed in the savings account. Select the equation of the bank that has the greatest compound interest rate.
A. f(t) = P(1.07)^t
B. f(t) = P(1.03)^2t
C. f(t) = P(0.90)^t
D. f(t) = P(1.02)^4t

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

i believe that the answer is

b. y-1=-2(x-4)

hope this !
