Answer:

11a. m <1 = 131 12a. m <1 = 42

11b. m <2 = 49 12b. m <3 = 75

11c. m <3 = 131 12c. m <4 = 42

11d. m <4 = 49 12d. m <5 = 63

11e. m <5 = 131 12e. m <6 = 75

11f. m <6 = 49 12f. m <7 = 105

11g. m <8 = 49 12g. m <8 = 75

11h. m <9 = 92 12h. m <10 = 75

11i. m <10 = 88 12i. m <11 = 42

11j. m <11 = 92 12j. m <12 = 138

11k. m <12 = 88 12k. m <13 = 42

11l. m <13 = 92 12l. m <14 = 138

11m. m <14 = 88

11n. m <15 = 92

Diane sold t-shirts at a festival and made a profit of $84 . She made $6 for each t-shirt she sold. Her total expenses were $30.

sweet-ann [11.9K]

Answer:

9 t-shirts

Step-by-step explanation:

Well if she made a profit of $30 that would mean that you would subtract $84-$30 which would give you $54. Than you would divide 54/6 to find how much t-shirts she sold.
