Answer:

60 rolls

Explanation:

first thing you want to do is add 3.50 +2.25 = 5.75

Then you divide 347.50 by 5.75

which is 60.34...

if you round that off it will be 60 rolls

Answer:

y=72

x=53

there are 72 packages

Explanation:

3.5x+2.25y=347.5

x+y=125

Thereby y=125-x

so

3.5x+2.25(125-x)=347.5

3.5x-2.25x+281.25=347.5

1.25x=66.25

x=53

53+y=125

y=72
