we need to divide the number of toy dinosaurs, 156, by the number of brothers, 4:

in order to estimate, we can use compatible numbers:

156 ÷ 4

  ↓

160   ÷ 4 = 40        

the correct answer is a).

meaning of term low   inflation is when prices of commodities does not change very highly.so low inflation is   not a sign of healthy economy.the demand of goods becomes higher due to some faulty measures taken by government

there are two kind of inflation

1. positive inflation : when supply of goods is less than prices of those goods rise.

2. negative inflation : when supply of any good is very high so it,s price will fall.

so option c is true : struggling economy because it results from a steady rise in demand.
