Jeremy wants to raise at least $80 in a fundraiser at a walk-a-thon. His dad has agreed to donate $3 for each mile that he walks, plus an additional $20. Write and solve the inequality based on this problem

Step-by-step explanation:

Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 2 h, and Car B traveled the distance in 1.5 h. Car B traveled 15 mph faster than Car A.

How fast did Car B travel?

(The formula  R⋅T=D , where R is the rate of speed, T is the time, and D is the distance can be used.)

Enter your answer for the box.

mph

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:
