Define a variable and write an algebraic expression for each problem. Evaluate the expression for the given values. 1. The charge for ice skating is $3 for skate rental and $2 per hour to skate. How much will you pay if you skate for: a) 2 hours? b) 4 hours? c) 3 1/2 hours?

Amount = 3 + 2t

Amount pay for 2 hours = $7

Amount pay for 4 hours = $11

Amount pay for 2 hours = $10

Step-by-step explanation:

Given:

Fixed charges = $3

Variable charges = $2 per hour

Find:

Amount pay

a) 2 hours? b) 4 hours? c) 3 1/2 hours?

Computation:

Assume time = t

So,

Amount = 3 + 2t

Amount pay for 2 hours = 3 + 2t = 3 + 2(2) = $7

Amount pay for 4 hours = 3 + 2t = 3 + 2(4) = $11

Amount pay for 2 hours = 3 + 2t = 3 + 2(3 1/2) = $10

So

don't give

take it once

try and try and you will not

happy to

pls mark as brainliest

one set of data has more variation than the other. hope this !
