Betty purchased two hotdogs and one soda for $11. Jose and his family purchased two hotdogs and three sodas for $17. Write an equation for Betty’s purchase using “h” for the price of a hotdog and “d” as the price of a soda. Do the same for Jose’s purchase. Determine the cost of a hotdog and a soda.

Can Someone do the whole problem and show explanation??

diyadiya · Answer

Betty purchased two hotdogs and one soda for $11
2h+1s=11

 Jose and his family purchased two hotdogs and three sodas for $17
2h+3s=17

anonymous · Answer

2h+d=11
2h+3d=17

... is this what you're asking ? :P

hoblos · Answer

for  Betty:  2h+d =11
for  Jose:   2h+3d =17

can solve this system now?

diyadiya · Answer

Oops sorry that was d instead of s :D

Betty purchased two hotdogs and one soda for $11
2h+1d=11

 Jose and his family purchased two hotdogs and three sodas for $17
2h+3d=17

diyadiya · Answer

Can you solve now?

anonymous · Answer

can u solve it and show explanation im learning how to solve problems thats why i want to see how the people do it

diyadiya · Answer

You can use either Substitution or elimination method here

Subtract the two equations

2h+3d =17
2h+  d =11
____________
 0+2d= 6

2d=6 
divide both sides by2 
2d/2=6/2
d=3

anonymous · Answer

ok so then what comes up next?

anonymous · Answer

is that it?is that the answer?

diyadiya · Answer

NO now we have to find h
we have just found out d (that's the price of soda) 

Now put the value of d in any of the equation and find out h

diyadiya · Answer

2h+  d =11
2h+ (3) =11
subtract 3 from both sides 
2h + 3 -3 = 11 -3
2h=8

divide by 2 
2h/2 =8/2
h=8/2 h= ?

anonymous · Answer

oh ok so we already found the answer for price Of soda now we just need to find h Right?

diyadiya · Answer

Yup =D

anonymous · Answer

so d =11?

anonymous · Answer

h=17 correct?

diyadiya · Answer

Nope

diyadiya · Answer

i just solved for d 
see

Subtract the two equations

2h+3d =17
2h+  d =11
____________
 0+2d= 6

2d=6 
divide both sides by2 
2d/2=6/2
d=3

so d=3 got it?

anonymous · Answer

oh yes i go it

diyadiya · Answer

Now since we have found out d 

we can find h from any of the above equation by subtituting the value of d

so now i take this equation

2h+  d =11

we know the value of d (d=3)
So
2h+ 3 =11

Now can you find h?

anonymous · Answer

i got h=4

diyadiya · Answer

Yes thats Right =)

anonymous · Answer

thanx alot for the help but how can i type in my answer for this question?

diyadiya · Answer

type where?
