In the equation A=1p+pri, t is equivalent to ( question 12 )

t = A - p/pr

Step-by-step explanation:

A = p + prt

A = p(1 + rt)

/p       /p

A/p = 1 + rt

-1       -1

A/p - 1 = rt

/r            /r

A/pr - 1/r = t

t = A - p/pr

t = A - p/pr

Step-by-step explanation:

bring a and the rest of the values to one side

its d but looking at that hurts my eyes frfr

step-by-step explanation:

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:
