Q. Bethany sells roses and petunias. The expression 3r+2.5p3r+2.5p gives the cost, in dollars, of rr roses and pp petunias. What is the cost, in dollars, of 77 roses and 88 petunias?\newline◻
  1. Calculate Roses Cost: Calculate the cost of 77 roses using the expression 3r3r, where rr is the number of roses.\newline3×7=213 \times 7 = 21 dollars for roses.
  2. Calculate Petunias Cost: Calculate the cost of 88 petunias using the expression 2.5p2.5p, where pp is the number of petunias.\newline2.5×8=202.5 \times 8 = 20 dollars for petunias.
  3. Find Total Cost: Add the cost of roses and petunias to find the total cost. 21+20=4121 + 20 = 41 dollars total.
