5. it is estimated that the annual cost of driving a certain new car is given by the formula
c = 0.35m + 2200
where m represents the number of miles driven per year and cis the cost in dollars. jane
has purchased such a car and decides to budget between $6400 and $7100 for next year's
driving costs. what is the corresponding range of miles that she can drive her new car?

three-fourths of an hour

36÷48=0.75

0.75=

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:

7,24
