$21+7.50p\leq 52$

<h2>Explanation:</h2>

For inequalities, "a is no more than b" can be written as:

$a\leq b$

Here we know Candace that can spend no more than $52 before tax. She can spend a certain amount of money in both Dark Roast coffee and Morning Blend coffee. So she spends:

2 pounds of Morning Blend coffee.
p pounds of Dark Roast coffee

Therefore:

<u>Amount of money for Morning Blend coffee:</u>

$2\times 10.50=\$21$

<u>Amount of money for Dark Roast coffee:</u>

$p\times 7.50=\$7.50p$

So the total amount of money:

$21+7.50p$

Finally, the inequality becomes:

$21+7.50p\leq 52$

Besides, in order to know how many pounds she can spend let's solve for p:

$7.50p\leq 52-21 \\ \\ 7.50p\leq 31 \\ \\ p\leq 4.13$

So she can spend less that 4.13 pounds.
