Adeposit of $5,000 is made into a savings account that offers 7.5% annual interest. which equation models the amount of money in the account after t years?
p(t) = 5,000(1.75)t
p(t) = 5,000(1.075)t
p(t) = 5,000(0.925)t
p(t) = 5,000(0.25)t

Step-by-step explanation:

Given: The initial deposit = $5000

The rate of annual interest = 7.5% = 0.075

We know that the exponential growth equation is given by :-

, where A is the initial amount, r is the rate of interest in x years.

Thus, for the given situation, the equation models the amount of money in the account after t years is given by :-

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
