Eunice wanted to save up for a mountain bike that costs £250. She baby-sits each week for 6 hours for £2.75 an hour, and does a Saturday job that pays £27.50. She saves 3/4 of her weekly earnings. How many weeks will it take her to save enough to buy the bike?

Approximately 2 weeks

Step-by-step explanation:

Given data

Total earnings for the week

=£27.50+£99

=£126.5 weekly

Hence it will take her

=1.97 week

Approximately 2 weeks to save up the amount
