Answer:
D i think
Step-by-step explanation:
6.70-10.00=3.30
So you get $3.30 as change
Answer: X=40
Step-by-step explanation:
Scale : 1 inch = 30 miles
So, the ratio between the distance on the map and the real distance is 1:30
When a quantity increase/decrease in a ratio, the other one increase/decrease respectively.
Call the miles we have to go : x
1:30 = 4.5:x
(1x4.5):(30x4.5) = 4.5 : x
4.5 : 135 = 4.5 : x
So, x = 135 => We have to go 135 miles to get to the place we want to go.
An expression for that would be s + 0.05s, or 1.05s.
