Sagot :

Let's break down each problem step-by-step.

### Problem 1
Christina has 8 sweaters. Danielle has 7 more sweaters than Christina.

- Christina's sweaters: 8
- Danielle's sweaters: [tex]\( 8 + 7 \)[/tex]

Calculating,

[tex]\( 8 + 7 = 15 \)[/tex]

So, Danielle has 15 sweaters. Hence, the first part of the answer is [tex]\( \boxed{15} \)[/tex].

### Problem 2
Kelly spent [tex]\(\$ 7.37\)[/tex] at McDonald's and paid with a [tex]\(\$ 20.00\)[/tex] bill. We need to determine how much change she will get back.

- Amount spent: [tex]\(\$ 7.37\)[/tex]
- Amount paid: [tex]\(\$ 20.00\)[/tex]

The change is calculated as,

[tex]\( 20.00 - 7.37 = 12.63 \)[/tex]

So, Kelly will get back [tex]\(\$ 12.63\)[/tex]. The correct option here is [tex]\( \boxed{c. \$ 12.63} \)[/tex].

### Problem 3
Victor, Jose, Joshua, Eric, and Danny went to a baseball game, and each ticket costs [tex]\(\$ 10.00\)[/tex].

- Number of people: 5
- Cost per ticket: [tex]\(\$ 10.00\)[/tex]

The total amount spent is,

[tex]\( 10.00 \times 5 = 50.00 \)[/tex]

So, they spent a total of [tex]\(\$ 50.00\)[/tex]. The answer is [tex]\( \boxed{50.0} \)[/tex].

### Problem 4
Lucille has 12 Barbie dolls, and each doll has 5 dresses.

- Number of dolls: 12
- Dresses per doll: 5

The total number of dresses is,

[tex]\( 12 \times 5 = 60 \)[/tex]

So, Lucille has 60 Barbie dresses altogether. The correct option here is [tex]\( \boxed{d. 60} \)[/tex].

### Summary of Answers:
1. Danielle has [tex]\( 15 \)[/tex] sweaters.
2. Kelly will get back [tex]\( \boxed{\$ 12.63} \)[/tex].
3. They spent a total of [tex]\( \$ 50.00 \)[/tex] for the tickets.
4. Lucille has [tex]\( 60 \)[/tex] Barbie dresses in total.
