Smart chart compares the number of pencils sold by two shops in a week: Shop A – 120, 135, 128, 140, 150. Shop B – 115, 140, 130, 145, 138. Which shop sold a higher total number of pencils in the week?

Step-by-step solution

1. Sum Shop A's sales: $120+135=255$; $255+128=383$; $383+140=523$; $523+150=673$.
2. Sum Shop B's sales: $115+140=255$; $255+130=385$; $385+145=530$; $530+138=668$.
3. Compare totals: $673$ (Shop A) > $668$ (Shop B).
4. Therefore Shop A sold a higher total.
