The sushi comes in rolls, and each roll contains 12 pieces and costs $8 Let R represent the number of additional rolls that Sofia orders

Sofia has ordered 24 pieces

Sofia needs 100 pieces

sushi comes in rolls

12 pieces per roll

= 12R

24 + 12R ≤ 100

(Choice C) 24+12R ≤100

B.

24 + 12R ≤ 100

12R ≤ 100 - 24

12R ≤ 76

R ≤ 76 / 12

R ≤ 6.33

Approximately 7 rolls

Sofia will order 7 more rolls

Each roll cost $8

R ≤ 7

7 × 8
