Arental car agency charges $160.00 per week $0.15 per mile to rent a car. how many miles can you travel in one week for $257.60

Firstly Subtract the weekly charge from the total

257.60 - 160 = 97.6

So 97.6 was charged for miles travelled

Since we know one mile is for 0.15, we divide

97.6 ÷ 0.15 = 650.7

Therefore 650.7 miles were travelled.

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:

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
