Question

Martin makes b bags of snack mix. Each bag contains 1.5 lb of nuts and 0.75 lb of dried fruit. What does the expression 1.5b + 0.75b represent?

Pls explain why​

Answer 1

1.5b + 0.75b represents the total amount of nuts and dried fruit used for b bags of snack mix.

b is the number of bags of snack mix, so the expression 1.5b means 1.5 multiplied by b, which is the total amount of nuts used for b bags of snack mix. Similarly, 0.75b is 0.75 multiplied by b, which is the total amount of dried fruit used for b bags of snack mix.

Adding these together gives us 1.5b + 0.75b, which is the total amount of nuts and dried fruit used for b bags of snack mix.
