It is.........................................................
2a + 2s = 32, 6a + 7s = 106
Solve for a in the first equation.
2a = 32 - 2s
a = 16 - s
Substitute a into the second equation.
6(16 - s) + 7s = 106
96 - 6s + 7s = 106
96 + s = 106
s = 10
Substitute s into the first equation.
2a + 2(10) = 32
2a + 20 = 32
2a = 12
a = 6
a = 6, s = 10

The formula to find the sample size :
Hence, the minimum sample size needed= 15.
-2+8
Bc 32 minus 34 is -2 then just add the 8
Answer:
Step-by-step explanation:
c is the number of cloth gloves sold.
r is the number of cloth gloves sold.
c + r =127
c = 127 - r
6.95c + 8.95r = 1070.65
6.95(127 - r) + 8.95r = 1070.65
882.65 + 2r = 1070.65
r = 94
c = 33
