X = 9
y = 6
Step by step:
Divide 15 by 2: 15 ÷ 2 = 7.5
Subtract 0.5 from 7.5 (this will later be added back): 7.5 - 0.5 = 7
Subtract 1 from 7 (she wants to buy at least 2 more children books): 7 - 1 = 6
Subtract 6 from 15 (6 being the number of puzzle books, 15 being the total number of items): 15 - 6 = 9 (number of children books)
Answer: 358 square units
Steps:
(12 * 20) + (10 * 10) + (6 * 3)
240 + 100 + 18
358
Imo you only need to be taught the basic of math and other things like geometry and algebra should be optional, although math is a core class along english/language arts which is why it’s necessary
