I bought ice cream and fritos. The firtos cost 64cents more than the ice cream. The total cost was $2.94. How much were the fritos?

Respuesta :

x=cost of ice cream
y=fritos
fritos is 0.64 more than ice cream
y=0.64+y

total is 2.94
x+y=2.94
subsitute


y=0.64+x
x+0.64+x=2.94
subtract 0.64 form both sides
x+x=2.30
divide by 2
x=1.15
subsiute
y=0.64+x
y=0.64+1.15=1.79

fritos=$1.79
