Her goal is to make at least $120 at least meaning is not less than 120, so the mathematical symbol is greater than or equal to >=. so the possible solution is let x be number of bracelety be the number of necklace6x + 10y >= 120 (5,9),(10,6),and(15,3)are three possible solutions.
Answer: 79
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
<u>Given information</u>
10x² - 7x + 10
x = 3
<u>Substitute the value into the expression</u>
= 10 (3)² - 7 (3) + 10
<u>Simplify by multiplication</u>
= 10 (9) - 21 + 10
= 90 - 21 + 10
<u>Simplify by subtraction</u>
= 69 + 10
<u>Simplify by addition</u>
= 79
Hope this helps!! :)
Please let me know if you have any questions
20 + 5x, is the equation I assume you're looking for. Do you need the table as well?
