Let x represent the amount of money Sophia can spend on party favors.
x = amount of money Sophia can spend
$2.75 = amount spent per person
6 = amount of people
Equation:-
x ÷ $2.75 = 6
Now lets solve for x :-
To solve for x we will use d INVERSE OPERATION of division which is multiplication. Lets do it:-
x ÷ 2.75 = 6
6 × 2.75 = x
6 × 2.75 = 16.50
x = 16.50
CHECK OUR WORK:-
x ÷ 2.75 = 6
x = 16.50
16.50 ÷ 2.75 = 6
We were RIGHT!!
So, our equation for dis question would be x ÷ 2.75 = 6. When we solve for x, x = 16.50. Sophia can spend $16.50 on her party favors for 6 people.
Hope I helped ya!! xD

Step-by-step explanation:
Question B:
Number of boys = 6
Number of girls = 4
Number of people in committee = 3
Number of ways of selecting committee with atleast 2 girls :
We either have :
(2 girls 1 boy) or (3girls 0 boy)
(4C2 * 6C1) + (4C3 * 6C0)
nCr = n! ÷ (n-r)!r!
4C2 = 4! ÷ 2!2! = 6
6C1 = 6! ÷ 5!1! = 6
4C3 = 4! ÷ 1!3! = 4
6C0 = 6! ÷ 6!0! = 1
(6 * 6) + (4 * 1)
36 + 4
= 40 ways
