Answer 1

We have the next information

he has $ 25.97

he wants to buy

one canvas that cost $14

and paint pens that cost $3.15 each

x is the number of paint pens

the inequality for this problem will be

$14+3.15x\le25.97$

the equal less than is that we can't buy over this quatity

we need to isolate the x in order to find how many paint pens Hamish can buy

$\begin{gathered} 3.15x\le25.97-14 \\ 3.15x\le11.97 \\ x\le\frac{11.97}{3.15} \\ x\le3.8 \end{gathered}$

Hamish can buy 3 paint pens
