Answer:
3
Step-by-step explanation:
the equation would be 5 = 3(3) - 4
which is 9 - 4 = 5
The answer is 2(7a+4) because using distributive property 2 times 7a is 14a and 2 times 4 is 8 so it equals 14a+8
Regular price: $419
Sale price: (1-0.205)($419) = $333.11
The bike will cost $333.11 before tax. You haven't shared the tax rate, but I can at least tell you that the cost of the bike after tax will be
(1.00 + rate as a decimal fraction)*$333.11.
Example: If the tax rate is 7.5%, then the bike will cost (1.00+0.075)*($333.11).
$1 = 3.70 rand
$450 is the same as 450 * $1, so multiply both sides of the conversion equation above by 450.
450 * $1 = 450 * 3.70 rand
$450 = 1665 rand
