[(284.1 x 105) - (1.100 x 10%)] x 2.8929

86,296.33523

Step-by-step explanation:

[(284.1×105) - (1.100×10%)] × 2.8929

=[29830.5 - 0.11] × 2.8929

=29830.39 × 2.8929

=86296.33523

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:
