feet and inches
flour and bread

the conversion factor between feet and inches
the amount of flour in a bread recipe
the price of a gallon of gas

Sav [38]

The total profit received for all mobile phone manufacturers for all carriers was 1.54 billion

Step-by-step explanation:

Profit received = 32%

Total profit received = $4.8 billion

Amount of profit received for mobiles = 32% of total profit

Amount received = $\frac{32}{100}*4.8$

Amount received = $\frac{153.6}{100}$

Amount received = 1.536 billion

Rounding off

Amount received = 1.54 billion

The total profit received for all mobile phone manufacturers for all carriers was 1.54 billion
