To solve for x and y, we can use the following equations based on the information given:
1.) 78% of x is 3.822:
0.78x = 3.822
x = 3.822/0.78
x ≈ 4.900
Therefore, 78% of x is approximately 3.822 when x is approximately 4.900.
2.) y% of 8 is 0.248:
(y/100)8 = 0.248
y/100 = 0.248/8
y/100 = 0.031
y = 0.031100
y = 3.1
Therefore, y% of 8 is 0.248 when y is equal to 3.1.
