A) (shirts) 12 multiplied by 3 is 36. (jeans) 19 multiplied by 2 is 38. 38 plus 36 equals 74. 74 minus 3 is 71. her total is 71 dollars
B) (shirts) 9 multiplied by 3 is 27. 16 multiplied by 2 is 32. 27 plus 32 is 59.
C) well there is obviously a difference between 71 and 59. 71 minus 59 is 12 dollars.
D) if i was the owner i would say "3 dollars off TOTAL purchase".
Step-by-step explanation:
x = price of 1 bush
y = price of 1 flower
12x + 30y = 240
7x + 10y = 125
the easiest approach is now to e.g. multiply the second equation by -3 and then add both equations, and then solve the result for x.
12x + 30y = 240
-21x - 30y = -375
-----------------------------
-9x 0 = -135
-9x = -135
9x = 135
x = 15
7x + 10y = 125
7×15 + 10y = 125
105 + 10y = 125
10y = 20
y = 2
so, each bush costs $15, each flower costs $2.
Answer:
it would be 101 i believe
