Answer:
19/4 or 4.75
Step-by-step explanation:
Week 1: 1 1/8 = 1.125
Week 2: -2 5/8 = -2.625*
Week 3: 1 3/4 = 1.75
Week 4: -1 1/2 = -1.5
Week 5: 2 1/8 = 2.125*
2 1/8 - (-2 5/8) = 2.125 - (-2.625)
19/4 or 4.75
Let the number of apples be x and that of pears be y, then:
0.64x + 0.45y = 5.26 . . . (1)
0.32x + 0.39y = 3.62 . . . (2)
(2) x 2 => 0.64x + 0.78y = 7.24 . . . (3)
(1) - (3) => -0.33y = -1.98
y = -1.98 / -0.33 = 6
From (2), 0.32x + 0.39(6) = 3.62
0.32x = 3.62 - 2.34 = 1.28
x = 1.28 / 0.32 = 4
Therefore, he bought 4 apples and 6 pears.
