The Blackbird Oil Company is considering the purchase of 20 new jumbo oil storage tanks. The standard model holds 12,000 gallons. Its dimensions are the size of the similarly shaped jumbo model, that is, the ratio of the dimensions is 4:5.How much more storage capacity would the twenty jumbo models give Blackbird Oil?

The 20 jumbo models will give Blackbird Oil a total storage capacity of 300,000 gallons.

If the ratio is 4:5, it means that the jumbo tanks are 1.25 times larger than the regular ones.

12000 x 1.25 = 15000

Each tank is 15000.

Multiply 15000 by 20 and you have 300000.
