Question

90 gallons increased by 130%
those are the answers and it’s not 117

Answer 1

Increasing by 130% means 100%+130% = 230% of the original value

90 x 230% = 90 x 2.30 = 207 gallons

Answer 2

130% of 90 gallons

= (130/100) × 90 gallons

= 117 gallons

So, total number of gallons

= 130 + 117

= 247
