WHat do you mean when you say you don't know "which graph is which"
If the number of adult tickets are taken as x then the number of children’s tickets can be taken as (89 — x ) then we can set up the equation
4.10(x) + 2.70 (89 — x) = 331.30
4.10x + 240.3 — 2.70x = 331.30
1.4x = 331.30 — 240.30
1.4x = 91
X = 65
Therefore 65 adult tickets and 24 children tickets as 89 — 65 is 24
as the product of 90 degrees and 20 degrees
30x60=1800
90x20=1800
Ok so what we need to find is 3 years of the simple interest so let’s get to it!
Ok so we found the principal price which is 250.00
And our rate is going to be 2.85%
A=P(1+rt)
Therefore the answer is going to be A=$271.38, therefore from the simple interest on a principal of $250.00 at a rate of 2.85% per year for 3 years is $271.38.
The correct answer is true, hope this helps!
