Question

The school's Environmental Science Club has $500 of funds. Each time they go on a field trip, it costs

Answer 1

Given:

Total fund = $500

cost of each trip = $80

To find:

The an algebraic expression that represents the money the club has after going on field  trips.

Solution:

Let x be the number of field trips.

Cost of 1 field trip = $80

Cost of x field trip = $80x

We have, Total fund = $500.

So, the money the club has after going on field  trips is

$\text{Remaining money}=500-80x$

Therefore, the money the club has after going on field  trips is $(500-80x).
