Answer:
7
Step-by-step explanation:
Start with $30.
Subtract $5 for the admission: $30 - $5 = $25.
Now he has $25 to spend on rides. Each ride costs $3.5, so we divide $25 by $3.50.
$25/$3.50 = 7.14
Since the number of rides must be a whole number, he can go on 7 rides.
The first one has a lower unit price because 1 bag is 3 dollars and the other one is 1 bag is 5 dollars
The answer is g(x)= x+2^2
Percent means parts out of 100
120%=120/100=1.2
80%=80/100=0.8
'of' means multiply
1.2 times a=0.8 times b
a=12
1.2 times 12=0.8 times b
14.4=0.8 times b
divide both sides by 0.8
18=b
so
a=12
b=18
a+b=12+18=30
