Imani sold 1 package of sugar cookie dough and 2 packages of oatmeal cookie dough for a total of $31. Chelsea sold 1 package of sugar cookie dough and 10 packages of oatmeal cookie dough for a total of $135. Find the cost of one package of sugar cookie dough and one package of oatmeal cookie dough.

Answer 1

The cost of one package of sugar cookie dough and one package of oatmeal cookie dough is $5 and $13 respectively

Explanation:

Let us assume the cost of one package of sugar cookie dough be x

And for one package of oatmeal cookie dough be y

Now the equations are

x + 2y = $31

x + 10y = $135

Solve these two equations by adding minus sign

-8y = -$104

y = $13

And, for x

x + 2($13) = $31

x = $31 - $26

= $5

Hence, the the cost of one package of sugar cookie dough and one package of oatmeal cookie dough is $5 and $13 respectively
