Answer 2

3. Jorge spent $15 on music.

4. Yuko must earn $180 to buy the console.

5. Roberto makes 7 shots if he attempts 20 shots.

6. Samantha ate cereal on 292 days in that year.

Let's solve each problem:

3. Jorge spent 30% of $50 on music. To find out how much money he spent, multiply $50 by 0.30 (which is 30% expressed as a decimal):

`\text{Amount spent} = 0.30 * 50 = 15`

Therefore, Jorge spent $15 on music.

4. Yuko's parents will pay for 40% of the $300 video game console. To find out how much Yuko must earn, multiply $300 by 0.60 (100% - 40%):

`\text{Amount Yuko must earn} = 0.60 * 300 = $180`

Yuko must earn $180 to buy the console.

5. Roberto makes 35% of the shots he attempts. If he attempts 20 shots, multiply 20 by 0.35 to find out how many shots he makes:

Number of shots made=0.35×20=7

Therefore, Roberto makes 7 shots if he attempts 20 shots.

6. Samantha ate cereal for breakfast on 80% of the days in a year with 365 days. To find out how many days she ate cereal, multiply 365 by 0.80 (80% expressed as a decimal):

Number of days Samantha ate cereal

= 0.80× 365=292

Number of days Samantha ate cereal=0.80×365=292

Samantha ate cereal on 292 days in that year.
