Darcy, Jason, and Maria share 268 dollars. Jason has 20 dollars more than Darcy and Maria has twice as much as Jason. How much m

frosja888 [35]

Answer:

The amount of money that Darcy and Jason have together is $124

Step-by-step explanation:

Let

x -----> amount of money that Darcy has

y -----> amount of money that Jason has

z ----> amount of money that Maria has

we know that

$x+y+z=268$ ------> equation A

$y=x+20$ -----> $x=y-20$ -----> equation B

$z=2y$ -----> equation C

substitute equation B and equation C in equation A and solve for y

$(y-20)+y+2y=268$

$4y-20=268$

$4y=268+20$

$4y=288$

$y=72$

Find the value of x

$x=y-20$ -----> $x=72-20=52$

The amount of money that Darcy has is $52

The amount of money that Jason has is $72

therefore

$52+$72=$124

The amount of money that Darcy and Jason have together is $124

Amir can travel 121.72 miles on 6.8 gallons of gas.

ASHA 777 [7]

The unit consumption of gas can be obtained by dividing the total distance traveled in miles by the total gallons of gas consumed by the trip. This is shown below:

121.72 miles / 6.8 gallons = 17.9

Therefore, on a gallon of gas, Amir can travel 17.9 miles, which is letter B among the choices.
