HELP 7TH GRADE MATH 3 QUESTIONS GIVING BRANLIEST

Step-by-step explanation:

3. The price was $7.50

Increasing by 20%,

20% of $7.50 is 7.50 × 20/100

= 750/100 × 20/100

= 75/10 × 2/10

= 15/2 × 1/5

= 3/2 × 1

= 3/2

Increasing by 20% = $7.50 + 3/2

750/100 + 5/2

75/10 + 5/2

75/10 + 15/10 = (75+15)/10 = 90/10 = $9
