Sonny has $5 to buy pencils and rulers. Pencils are 8 cent each. Rulers are 30 cent each. She says “I will buy 15 pencils. Then I will buy as many rulers as possible. With my change I will buy more pencils.” How many pencils and how many rulers does she buy? 17 pencils, 12 rulers 18 pencils, 12 rulers 17 pencils, 10 rulers 12 pencils, 14 rulers.

12 Rulers and 17 Pencils

Step-by-step explanation:

15 x 8 = cents spend

15 x 8 = 120

$5-120cents ($1.2) = $3.8 (380 cents)

380/30= 12 rulers with 20 cent remaining

20/8= 2 pencils with 4 cent remaining

now add

12 ruler +2 pencils +15 pencils=

12 Rulers and 17 Pencils
