Answer:

Flour
$5(1)/(2)\ c$

Sugar
$2(2)/(3)\ c$

Butter
$1(1)/(2)\ c$

Eggs

Baking powder
$7\ t$

Vanilla extract
$3\ t$

Explanation:

There will be 16 people at the party. Each person will eat 3 cookies, so all people will eat
$16\cdot 3=48$ cookies.

Given cookie recipe makes 24 cookies, so to make 48 cookies you need

48:24=2 portions.

Thus,

1 portion 2 portions

Flour
$2 (3)/(4)\ c$
$2(3)/(4)\cdot 2=2\cdot 2+(3)/(4)\cdot 2=4+(3)/(2)=4+1 (1)/(2)=5(1)/(2)\ c$

Sugar
$1(1)/(3)\ c$
$1(1)/(3)\cdot 2=1\cdot 2+(1)/(3)\cdot 2=2+(2)/(3)=2(2)/(3)\ c$

Butter
$(3)/(4)\ c$
$(3)/(4)\cdot 2=(3)/(2)=1(1)/(2)\ c$

Eggs

$1\cdot 2=2$

Powder
$3(1)/(2)\ t$
$3(1)/(2)\cdot 2=3\cdot 2+(1)/(2)\cdot 2=6+1=7\ t$

Vanilla
$1(1)/(2)\ t$
$1(1)/(2)\cdot 2=1\cdot 2+(1)/(2)\cdot 2=2+1=3\ t$
