Question
I'm twelve and my parents and i cant figure this out! can you help me find an equation that will that will solve the problem- if two hot dogs and 1 hamburger cost $3.39 and 3 hot dogs and 3 hamburgers cost $6.57 how much does one hot dog cost?
ok its a simple system of equations
x = hotdogs
y = hamburgers
2x + y = 3.39
3x + 3y = 6.57
now just solve.
2x + y = 3.29
y = -2x + 3.29
3x + 3y = 6.57
3x + 3(-2x + 3.29)= 6.57
3x - 6x + 9.87 = 6.57
-3x + 9.87 = 6.57
-3x = -3.3
x = 1.1
which means each hot dog is $1.10. Hope this makes sence.
