Answer:
<em>Rental cost</em> of <em>movie</em> is <em>$6.50</em><em> ; </em><em>Rental cost</em> of <em>video game</em> is <em>$2.25</em>
Step-by-step explanation:
4m + 8v = 61 ........ <em>(1)</em>
2m + 3v = 24 ........ <em>(2)</em>
<em>(1)</em> - 2 × <em>(2)</em>
2v = 13
v = 6.5
2m + 3(6.5) = 24
2m = 24 - 19.5
m = 4.5 ÷ 2 = 2.25
<em>Rental cost</em> for each <em>movie</em> is <em>$6.50</em>
<em>Rental cost</em> for each <em>video game</em> is <em>$2.25</em>
You can determine if a number is rational if it can be represented as a terminating or repeated decimal, but if it can not, then the number is irrational.

Answer:
A) Isaac should get £ 10.75 in change.
B) The price of the e-scooter in the sale is £ 366.3.
Step-by-step explanation:
A) Given that Isaac buys 17 anti-pollution masks for £ 5.25 each, and he pays with five £ 20 notes, to determine how much change Isaac should get, the following calculation must be performed:
(20 x 5) - (17 x 5.25) = X
100 - 89.25 = X
10.75 = X
So Isaac should get £ 10.75 in change.
B) Given that the normal price of an e-scooter is £ 370 and, in a sale, there is 1 off the normal price of the e-scooter, to determine the price of the e-scooter in the sale the following calculation must be performed:
370 - (370 x 0.01) = X
370 - 3.7 = X
366.3 = X
Thus, the price of the e-scooter in the sale is £ 366.3.
