Let the cost of one pound of candy be x and one pound of mint be y.

3x+2y=10.8 a
x+3y = 5.35 b
B*3 = 3x+9y = 16.05 b

b-a = 7y = 16.05-10.8= 5.25
y = 5.25/7 = 0.75

The cost per pound of mints is $0.75

Use the quadratic formula to solve the equation to the exact value or round to two decimal places.

First set everything to 0.
${x}^{2} + x - 5$
Giving you A= 1 , B= 1 and C= -5
Then input everything into the quadratic formula and either solve by hand or use a calculator.
Note exact values are found by hand, decimals are found using a calculator.
