a) 2 pounds of Sour Patch Kids
b) 3 pounds of Rolos
Step-by-step explanation:
Given,
Pounds of candy bought = 5 pounds
Cost of sour patch per pound = $2.25
Cost of Rolos per pound = $1.75
Total amount spent = $9.75
Let,
x = Number of pounds of sour patch
y = Number of pounds of rolos
x+y=5
x = 5-y Eqn 1
2.25x+1.75y=9.75 Eqn 2
Putting value of x from Eqn 2 in Eqn 1
Dividing both sides by 0.5
Putting y = 3 in Eqn 1
