Robin and Emily are selling boxes of candy bars. Robin sells 36 boxes of candy and Emily sells 24 boxes of candy. Which expression, using the form a(b+c), represents the amount they sold together
a. 2(12+24)
b. 4(9+6)
c. 24 (6 + 36)
d. 12 (3 + 2)
My answer is B
9+6=15x4=60
60 candy bars is what they sold together
Can you please double check my work and let me know if I got the correct answer.
b works but so does d
By the way two things have to happen.
a(b+c) = 60
and if ab = 36 then ac must be 24
Your answer is partially correct.
4 ( 9 + 6 ) = 4 * 15 = 60
But also:
36 = 12 * 3
24 = 12 * 2
36 + 24 = 12 * 3 + 12 * 2 = 12 ( 3 + 2 )
12 * ( 3 + 2 ) = 12 * 5 = 60
Answers b and d
To find the correct answer, we need to add the number of candy boxes sold by Robin and Emily together. Let's evaluate the options to find the correct expression:
a. 2(12+24)
Calculating the inside of the parentheses: 12+24 = 36
Then multiplying by 2: 36 x 2 = 72
b. 4(9+6)
Calculating the inside of the parentheses: 9+6 = 15
Then multiplying by 4: 15 x 4 = 60
c. 24(6+36)
Calculating the inside of the parentheses: 6+36 = 42
Then multiplying by 24: 42 x 24 = 1008
d. 12(3+2)
Calculating the inside of the parentheses: 3+2 = 5
Then multiplying by 12: 5 x 12 = 60
So, it seems your answer, option B, is correct. Robin and Emily together sold 60 boxes of candy bars. Well done!
