Foundation June 2018 Paper 2 Q16
16 Marla buys some bags of buttons.
There are 19 buttons or 20 buttons or 21 buttons or 22 buttons in each bag.
The table gives some information about the number of buttons in each bag.
| Number of buttons | Frequency |
|---|---|
| 19 | …… |
| 20 | 7 |
| 21 | 3 |
| 22 | 1 |
The total number of buttons is 320
Complete the table. (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| 5 | P1 | for start to process eg \(7 \times 20\ (= 140)\) and \(3 \times 21\ (= 63)\) or \((7 \times 20) + (3 \times 21) + 22\ (= 225)\) |
| P1 | for a complete process to find the missing frequency eg \((320 - \text{``}225\text{''}) \div 19\) or \(320 - \text{``}225\text{''} = (95)\) and \(\text{``}95\text{''} \div 19\) | |
| A1 | cao |
Additional guidance
May be written near table
\(7 \times 20\ (= 140)\) and \(3 \times 21\ (= 63)\) minimum requirement for P1
May be seen as two calculations
Please check the table.
