(80 pts) Alexandra bought 4 hamburgers and 3 drinks for her family. The cost was $18.25. Tyler bought 6 hamburgers and 4 drinks
at the same fast food restaurant for $26.50. What is the total cost of one hamburger and one drink?
2 answers:
3(4h+3d=18.25)-2(6h+4d=26.50)
12h+9d-12h-8d=54.75-53
d=1.75, use either original equation to solve for h...
4h+3(1.75)=18.25
4h+5.25=18.25
4h=13
h=3.25
So the cost of one hamburger and one drink is:
3.25+1.75=$5.00
H=hamburgers.
D=drinks
3(4h+3d=18.25) - 2(6h+4d=26.50)
12h+9d-12h-8d=54.75-53
d=1.75
4h+3(1.75)=18.25
4h+5.25=18.25
4h=13
h=3.25
cost of one hamburger and one drink is:
3.25+1.75=$5.00

Step-by-step explanation: im pretty sure because if you look at Ed its 5 and then if you add the same sides twice its 10 hopefully im right
2x=3
so substitute y=mx+c
