Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

What is the price per banana (in pence) at Fine Fare Supermarket?

Unnamed gapp/banana

Advice

a)

The pack price at Fine Fare supermarket is {b_pack}, which converted to pence is {b}p.

The price per banana at Fine Fare supermarket is

$\var{b} \div 5 = \var{b_single}\text{p.}$

b)

As the price at Hintons supermarket is cheaper, {person['pronouns']['they']} should shop there.

c)

The new price per banana at Fine Fare Supermarket is

$\begin{align} \var{b} \div 6 &= \var{if(isint(b/6),b/6,dpformat(b/6,1))}\text{p.} \\ \end{align}$

Since the price at Hintons Supermarket is still cheaper, {person['name']} should not change {person['pronouns']['their']} decision.

Since the price at Fine Fare Supermarket is now cheaper, {person['name']} should change {person['pronouns']['their']} decision.
