Question

At the local convenience store, 3 bags of chips and 2 containers of dip cost $9. However, 5 bags of chips and 7 containers of dip cost $26. What is the cost of one bag of chips and one container of dip?

Answer 1

make two eqns

Answer 2

3x+2y=59
5x+7y=26

Answer 3

then solve::
do u need further help..

Answer 4

I think so

Answer 5

did u get the two eqns'

Answer 6

from eqn i>
x=(59-2y)/3
substitute this value of x in second eqn
5x+7y=26
5 (59-2y)/3 +7y=26
(295-10y)/3+7y=26
295-10y+21y=26 X 3
11y=78-295
y=-217/11

x=(59-2y)/3
=(59-2 X(-217/11))/3
=(649-6293)/33
y=-5644/33

Answer 7

sry x=-5644/33

Answer 8

there may be some cal errors

Answer 9

Woha! that's alot!
a. chips = $2; dip = $2
b. chips = $1.50; dip = $2.50
c. chips = $3; dip = $4
d. chips = $1; dip = $3
these are the choices and i got b

Answer 10
