One package of sugar cookie dough costs $____. One package of double chocolate chip cookie dough costs $____

Answer 1

4s +22c = 230: equation I

20s 44c = 556 equation II

two equations 2 unknowns, solve by substitution elimination or linear algebra

s= $8 for sugar

c=$9 for chocolate

4(8) +22(9)

= 32 + 192

= 230

20(8) + 44(9)

= 160 + 196

= 556

1 package of one each = 8+9 = $17
