Answer:
They will need between 2520 to 2680 pounds of cookie dough.
Step-by-step explanation:
In order to figure out how many pounds of cookie dough the math club will need, we first need to know how many pounds of dough are sold per person.
Last year, the club sold 2,080 pounds of cookie dough to 520 people, this means the amount sold to per person is:
[tex]\frac{2080\:pounds}{520\:people} = 4\:pounds/person[/tex]
Thus for 630 people the amount of dough needed is
[tex]630*\frac{4\:pounds}{person} =2520\:pounds.[/tex]
and for 670 people
[tex]670*\frac{4\:pounds}{person} =2680\:pounds.[/tex]
Thus the amount of dough the club will need is between 2520 to 2680 pounds.
