max2010maxim [7]

Answer:

Step-by-step explanation:

Given:

Total money Jervane can spend = $20.

Cost of a coffee = $3.

Cost of a donut = $2.

To find: Maximum number of donuts Jervane can buy.

Solution:

Let the number of donuts she can buy be $x$ .

She wants to spend no more than $20 in total.

So,

$3+2x\leq 20$

$\Rightarrow 2x\leqslant 20-3$

$\Rightarrow 2x\leqslant 17$

$\Rightarrow x\leqslant \frac{17}{2}$

$\Rightarrow x\leqslant 8 \frac{1}{2}$

As the number of donuts can only be a natural number.

Hence, the maximum number of donuts that Jervane can buy are 8.
