Question

steph buys 12 bananas for $2 each. she also buys 7 sandwiches that are twice as much. the store has a $2 off sale on the sandwiches. numerical expression that shows how much she spent. then solve.

Answer 1

Well 12x 2 = 24       7x   (4) <because 2x2=4    so 7 x (4)=28  with a discount of 2 so 28-2 =26     and 26 + 24 = 50 :) hope this helps )

Answer 2

(12 x 2) + (7 x 4) - 2 would be the expression 
first you multiply the 12 x 2 and the 7 x 4, you add those together and then you subtract two from your total answer.
meaning your answer would be 50
