v stands for vegetarian wraps
c stands for chicken wraps

v + c = 70 ---> v = 70 - c
1.8c + 1v = 98.80

now sub 70 - c in for v in the second equation...
1.8c + 1(70 - c) = 98.80 (distribute the 1 through the parenthesis)
1.8c + 70 - c = 98.80 (combine like terms)
.8c + 70 = 98.80 (subtract 70 from both sides)
.8c + 70 - 70 = 98.80 - 70
.8c = 28.8 (divide by .8 to get c by itself)
.8c/.8 = 28.8/.8
c = 36

now sub 36 in for c in the first equation...
v + c = 70
v + 36 = 70
v = 70 - 36
v = 34

check...
1.8c + 1v = 98.80
1.8(36) + 1(34) = 98.80
64.8 + 34 = 98.80
98.80 = 98.80 (correct)

ANSWER : vegetarian wraps sold were 34 at $ 1 each = $ 34.00
               chicken wraps sold were 36 at $ 1.80 each = $ 64.80.
                total :  70 wraps at a total of $ 98.80
