Question

Lisa sold 15 cups of lemonade on Saturday

and twice as many on Sunday. Which
expression represents the total number of
cups of lemonade she sold on both days?


15+15

2×15

15+(2×15)

2x (15+15)

Answer 1

15+(2x15)

Explanation:

Saturday: she sold 15

Sunday: she sold twice as many which means 15x2=30

when you add them you'll get 45

so 15+(2x15)

first you do the parenthesis (2x15) =30

then you add 15 to 30 which gives you 45.
