Express the terms of the following geometric sequence by giving an explicit formula. 7, 28, 112.448 , 1,792, ...

A.) f(n) = 7(4)(n-1), where n = 1, 2, 3,...

B.) f(n) = 4(7"), where n = 1,2,3,...

C.) f(n) = 4(7)n-1, where n = 1, 2, 3,...

D.) f(n) = 7(4)n-1, where n = 1, 2, 3,...

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

the answer is 2/54
