Answer:

In April, the dollar increase 1.94% in Brasil's economy.

Explanation:

The given problem is about sum and difference between the increase and decrease of the dollar in Brazil.

We know that the dollar increased y% in April, 3.5% in May and decrease 2.4% in June. So, we can write the following equation.


y \% + 3.5 \% - 2.4\% = 3.04\%

Where we solve for
y\%


y \% + 3.5 \% - 2.4\% = 3.04\%\\y \% = 3.04 \% - 3.5 \% + 2.4 \% = 1.94 \%

Therefore, in April, the dollar increase 1.94% in Brasil's economy.
