Question

Write an algebra equation for each purchase. I bought an ice cream treat and a bottle of water for $10. Pam purchased an ice cream treat and two bottles of water for $14. Use your equations and reasoning skills to find the price of a bottle of water and an ice cream treat.

Answer 1

\[x + y = 10\]
\[x + 2y = 14\]

solve it simultaneously

Answer 2

do i multiply them/?

Answer 3

wht do u mean? multiply wt

Answer 4

What do i do with the numbers 10 and 14

Answer 5

Can u do the whole problem and show explanation?

Answer 6

its like this
\[x + y = 10\]
\[x + 2y = 14\]

x is common in both so u have to subtract the second one from 1st
x-x + y-2y = 10-14
-y = -4
y=4
which means bottle of water (y) = 4
and then substitute 4 in equation (x+y=10 or x+2y=10)
x + 4 = 10
x=6

Answer 7

Oh ok ;p i get what u did so x=6 and y=4 that would be my answer for the question correct?

Answer 8

yes it is in this case, bottle cost 4 dollars and icecream cost 6 dollars
so when the person buy an ice cream treat and bottle = 6+4 = 10
2nd time he buys an ice cream treat and 2 bottle = 6+ 2(4) = 14
there u get t
