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

  $5.68

Step-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

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
