A boutique wants to make at least $127 profit from purses this week. The boutique earns $7 profit from each purse. How many purses must be sold?

19 purses

Step-by-step explanation:

Set up an inequality where x represents the number of purses:

127 7x

Solve for x by dividing each side by 7:

18.14 x

Round up to 19 because purses have to be whole

So, 19 purses have to be sold.

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
