25% increase

Step-by-step explanation:

To find the percent increase write a proportion:

Then solve for x by cross multiplying numerator with denominator of each fraction:

20(100) = 16(x)

2000=16x

125 = x

This means from 100% then 125% is 25% increase.

1.5 hours

Step-by-step explanation:

Carlos = x

Maria = y

55x + 47y = 197

x + y = 3.8

x = 3.8 - y

55(3.8 - y) + 47y = 197

209 - 55y + 47y = 197

-8y = -12

y = 3/2 = 1.5
