You sign up for karate classes. The classes cost $80 per

month
Write an equation for the number of dollars, d, that
you pay for your karate classes if you take classes for
m months.
Complete the table for the missing values of d.
d
1
80
2
3
4
320

Answer 1

m* = d**

1 = $80

2 = $160

3 = $240

4 = $320

*months

**Dollars ($)

Explanation:

If it costs 80 per month then you times 80 by the number of months you want to work out. For example, you want to work out the cost of going to karate class for 3 months, and it costs $80 per month. Then you do $80 × 3 = $240.
