determine if there is a proportional relationship between the two quantities. explain your reasoning.
1) a b
35 92
23 80
2) c d
20 8
12.5 5
- the answer for 1) a and b is a and b are not proportional. the ratios of the values of a to b are not equal.
- the answer for 2) c and d are proportional. the ratios of the values of c to d are equal.
just explain how to know how to determine its proportional and not proportional.

Tomas is making trail mix using granola and walnuts. he can spend a total of $12 on the ingredients. he buys 3 pounds of granola that costs $2.00 per pound. the walnuts cost $6 per pound. he uses the equation to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. he solves the equation for y, the number of pounds of walnuts he can buy. answer- b tomas added 6 to both sides of the equation instead of subtracting 6. just took the test
