So times $64.80 by 2.5. You minus 20 from that, so that the RacerZ is $142. You take that $142 and times that by 1.09. You get 154.78. Therefore;
Speedmonster- 64.80
RacerZ- 142
Swiftee-154.78
Hope this helps. :)
To determine the total class the whole class spent, you just have to simply add the individual costs of the three books. Using parenthesis, the solution can be written in the following two ways:
($15 + $9) + $12 = $36
$15 + ($9 + $12) = $36
No matter where you put the parenthesis, the final answer doesn't change. This is because of the Commutative Property of Addition. The order does not matter.
Set up a ratio with height over shadow height:
40/30 = x/15
Cross multiply:
40 x 15 = 30x
600 = 30x
Divide both sides by 30:
X = 20
The tree is 20 feet tall.
X=1 is(1,10). This means in terms of the snake population that after a year the snake population doubled and it’s 10 snakes now
The pack of pens that has 12, is you bought 120 pens the total would be $90 but with the other pack it would cost $93.60
hope this helps!
