Foundation June 2023 Paper 1 Q18
18 Naomi has \(b\) bags of apples and \(c\) crates of apples.
There are 5 apples in each bag.
There are 28 apples in each crate.
Naomi has a total of \(T\) apples.
Write a formula for \(T\) in terms of \(b\) and \(c\). (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| \(T = 5b + 28c\) | M1 | for \(5b\) or \(28c\) or \(T =\) a linear expression in \(b\) and/or \(c\) |
| M1 | for \(5b + 28c\) or partially correct formula, eg \(T = 5b\ (+ kc)\) oe or \(T = 28c\ (+ kb)\) oe | |
| A1 | for \(T = 5b + 28c\) oe |
Additional guidance
Allow \(5 \times b\) and \(28 \times c\) throughout
