Answer:
150+55w
Step-by-step explanation:
150 never changes
(55)(w), 55 changes depending on number of weeks
The expression is: 150 + 55W
amount already in your a/c = $150
Amount saved per week = $55
Number of weeks to save for is W
Amount saved in W weeks is $55W
Total amount saved in W weeks is $150 + $55W
Ignoring the symbols, the expression is 150+55W
It is important because it allows you to calculate the surface area of a trapezoidal prism
It has no value.
