It is expected that gas prices will rise to be 142% of the current amount. If the current gas price is $4 per gallon, explain how to estimate the expected price of gas

Accepted Solution

Answer:   $5.68Step-by-step explanation:142% of the current price of $4 per gallon is found by multiplying these numbers:   142% × $4.00/gal = $5.68/gal_____Of course, you know that 142% = 142/100 = 1.42. The numbers get multiplied and the units ($/gal) get applied to the result.Multiplication by 4 is easily done mentally by doubling twice:   4×1.42 = 2×(2×1.42) = 2×2.84 = 5.68
