Answer:
2 3/4 pounds of lunch meat costs $6.6
Step-by-step explanation:
Maria bought 1 2/5 pounds of lunch meat for $3.36.
[tex]1\frac{2}{5} =\frac{1*5+2}{5} =\frac{7}{5}[/tex]
[tex]\frac{7}{5}[/tex] pounds of lunch = 3.36
1 pound of lunch = [tex]\frac{3.36}{\frac{7}{5}} = 3.36 * \frac{5}{7} =2.4[/tex]
So 1 pound of lunch costs $2.4
[tex]2\frac{3}{4} =\frac{2*4+3}{4} =\frac{11}{4}[/tex]
1 pound of lunch = 2.4
11/4 pounds of lunch = [tex]2.4* \frac{11}{4} =6.6[/tex]
