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
