9. Enrique would earn $7. 50 per hour. Option B

10. The number of girls that were at the assembly is 1390 . Option J

11. 40% of 60 is 24 . Option C

12. The simple interest is $72. 00 . Option F

13. The factory produces 1080 shoes on Tuesday. Option D

How to determine the value

9. From the information given, we have;

  • He earns $420
  • He works a total of 56 hours

He would earn;

= 420/ 56

= $7. 50 per hour

10. We have that;

  • There are 1200 boys at the assembly
  • Ratio of boys to girls is 20: 23

The number of girls at the assembly would be;

= 23/ 20 × 1200

= 1. 15 × 1200

= 1380

11. Let the number be x

40% of x = 24

40/ 100x = 24

0. 4 x = 24

Make 'x' the subject

x = 24/ 0. 4

x = 60

12. The formula for simple interest is expressed as;

Simple interest = PRT / 100

Simple interest = 300 × 4 × 6/ 100

Simple interest = 7200/ 100

Simple interest = $72. 00

13. We have that;

Monday's production = 900 shoes

Tuesday's production = 900 + 900 × 20% = 900 × 20/ 100 = 18000/ 100 = $900 + 180

= $1080

Thus, the total amount Enrique earns per hour is $7. 50 .Option B
