A store has 5 rings and 9 bracelets for sale. If all 14 items sell, how much money will the store take in? Choose the correct answer and explanation. $1,417 9 × $88 = $792; 5 × $125 = $625; $792 + $625 = $1,417 B. $1,427 9 × $88 = $802; 5 × $125 = $625; $802 + $625 = $1,427 C. $1,565 9 × $125 = $1,125; 5 × $88 = $440; $1,125 + $440 = $1,565 D. $2,982 5 + 9 = 14; $88 + $125 = $213; 14 × $213 = $2,982

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:

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
