Accepted Solution
A:
Sarah is selling bracelets. The inequalities are a > 10 and 2a + 3b ≥ 60.Solution:Given, Sarah is selling bracelets and earrings to make money for summer vacation. bracelets cost = $2 earrings cost = $3 She needs to make at least $60. Sarah knows she will sell more than 10 bracelets. We have to write inequalities
Now, according to given information, Total money ≥ $ 60
Money earned from bracelets + money earned by earrings ≥ 60
2 x number of bracelets + 3 x number of earrings ≥ 60
2a + 3b ≥ 60 [ where a is number of bracelets and b is number of earrings]And, number of bracelets is more than 10 ⇒ a > 10
Hence, the inequalities are a > 10 and 2a + 3b ≥ 60
