Joe scored 43 in Economics, 31 in Science and 52 in Math. What is his total in all the three subjects? a. 115 b. 126 c. 95 d. 136

#### Solution:

Total score = marks in Economics + marks in Science + marks in Maths.

= 43 + 31 + 52
[Substitute the values.]

43 = 40 + 3
31 = 30 + 1
52 = 50 + 2
[Break the numbers into tens and ones.]

= (40 + 30 + 50) + (3 + 1 + 2)
[Add the tens and ones separately.]

= 120 + 6 = 126
[Add the two sums.]

So, the total in all the three subjects is 126.
