candace is at a coffee shop and knows she can spend more than $52 before tax she sees this price list in the coffee shop
dimulka [17.4K]

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.
