Step-by-step explanation:
Mr. Leonard gets £ 45.84375 as discount
<em><u>Solution:</u></em>
The oil tank can take up to 1200 liters of oil
There are already 450 liters of oil in the tank
The remaining oil which is to be added is given by :
Remaining oil = 1200 - 450 = 750 liters
The price of oil is 81.5 p per liter
<em><u>Then calculate the total price of 750 L of oil:</u></em>
Thus total price is 61125 p
Mr Leonard gets a 7.5% discount on the price of the oil
Therefore,
Discount amount = 7.5 % of 61125
Thus he gets 4584.375 p
We convert p to £
1 p = 0.01£
4584.375 x 0.01 = £ 45.84375
Thus he gets £ 45.84375 as discount
Hello!
To solve each expression, you need to substitute the given value for each given variable. If there is an <em>x</em> in the expression, then you substitute 5.07. If there's a <em>y</em>, then you substitute 1.5, and if there's a <em>z</em>, then you substitute 0.403.
7. 3.2x + y (substitute x = 5.07 and y = 1.5)
3.2(5.07) + (1.5)
16.224 + 1.5
17.724
8. yz + x (substitute y = 1.5, z = 0.403, and x = 5.07)
(1.5)(0.403) + (5.07)
0.6045 + 5.07
5.6745
9. z × 7.06 - y (substitute z = 0.403 and y = 1.5)
(0.403) × 7.06 - (1.5)
2.84519 - 1.5
1.34518
<u>Final answers</u>:
- Number 7: 17.724
- Number 8: 5.6745
- Number 9: 1.34518
The answer is b
