The expression that represents the amount mother spent is 4 × 5.00 + 2.00.

This outing will cost $22.00.

Solution:

Number of members in a family = 4

Cost of one ticket = $5.00

Cost of soft drink = $2.00

Mother spent = Number of members × Cost of each ticket + Cost of soft drink

                      = 4 × 5.00 + 2.00

The expression that represents the amount mother spent is 4 × 5.00 + 2.00.

To solve this expression using PEDMAS rule.

First do multiplication.

4 × 5.00 + 2.00 = 20.00 + 2.00

Now do addition.

4 × 5.00 + 2.00 = 22.00

Hence this outing will cost $22.00.
