2. a. PHP 25.50 per hour x 4 hours= 102.00 PHP
b. This is quite confusing for me, so I'll give a lot of answers here.
If a student works for four hours per day for 3 days,
102 PHP x 3 days = 306 PHP
If a student works for 8 hours per day* for 3 days,
25.50 PHP per hour x 8 hours= 204 PHP
204 PHP x 3 days = 612 PHP
If a student works for 24 hours per day for 3 days,
PHP 25.50 per hour x 24 hours= 612 PHP
612 PHP x 3 days = 1836 PHP
3. 3.8 miles x 13 = 49.4 miles far from the first
4. Cost = PHP 30.20 per chocolate bar x 115 chocolate bars = PHP 3473
Weight = 8.7 g per chocolate bar x 115 chocolate bars = 1000.5 g
5. 95 kg of beef x PHP 180.90 per kg of beef = PHP 17185.50
*8 hours per day is the usual working hours.
