Sure, let's go through each problem one by one.
### Problem 1:
Christina has 8 sweaters in her closet. Danielle has 7 more sweaters than Christina. To determine how many sweaters Danielle has, you need to add the number of sweaters Christina has to the additional sweaters Danielle has.
Here's the arithmetic:
- Christina's sweaters: 8
- Additional sweaters Danielle has: 7
So, Danielle's sweaters = Christina's sweaters + additional sweaters
Danielle's sweaters = 8 + 7 = 15
So, Danielle has 15 sweaters.
### Problem 2:
Kelly spent [tex]$7.37 at McDonald's and paid with a $[/tex]20.00 bill. To figure out how much money Kelly will get back, you need to subtract the amount she spent from the amount she paid.
Here's the arithmetic:
- Amount paid: [tex]$20.00
- Amount spent: $[/tex]7.37
So, money returned = amount paid - amount spent
money returned = [tex]$20.00 - $[/tex]7.37 = [tex]$12.63
So, Kelly will get back $[/tex]12.63.
From the given options:
a. [tex]$9.53
b. $[/tex]11.63
c. [tex]$12.63
d. $[/tex]12.73
The correct answer is: c. [tex]$12.63
### Summary
1. Danielle has 15 sweaters.
2. Kelly will get back $[/tex]12.63, so the correct option is c. $12.63.
