There are 23 students in Ms. Jane’s class. Because you do 138/6 and you get 23.
48. 40% of 80 is 32. 80-32=48. Which means there are 32 boys and 48 girls.
Step-by-step explanation:
Let x be the amount Jennifer needs to spend more.
We have $112.49 + x >= $250.
We subtract $112.49 from both sides of the inequality to get x >= $137.51.
Hence, Jennifer needs to spend at least $137.51 more to earn the free T-shirt.
