1. A bakery produces several bread items and biscuits. In a packet, there are 8 buns of hot dogs. Some packets of hot dog buns cost $77700 which are produced in 5 days. How many packets of hot dog buns will it produce in a week if the cost of each packet of hot dog buns is $37?
a) 2100 packets
b) 2310 packets
c) 2720 packets
d) 2940 packets
Answer: d) 2940 packets
Explanation: Total cost of hot dog buns = $4088.50
Cost of each packet of hot dog buns = $37
Number of packets of hot dog buns produced in 5 days = 77700 ÷ 37
= 2100
Number of packets of hot dog buns produced in 1 day = 2100 ÷ 5
= 420
Number of packets of hot dog buns produced in 7 days (1 week) = 420 × 7
= 2940

= $(86.5 + 49.60)
= $136.10

Total amount in cents spent by her = $400.11 × 100 = 40011 cents
5. Joseph's car was parked in the parking lot from 6:30 a.m. to 11.45 a.m. How much does he have to pay?
a) $25.25
b) $26.25
c) $26.50
d) $26.75
Answer: d) $26.75
Explanation: Duration from 6.30 a.m. to 11.45 a.m. is 5 hours 15 minutes.
The parking rate for the first hour (6.30 a.m. to 7.30 a.m.) = $6.50
Now, parking rate for the remaining 8 half hours [4 hours] (7.30 a.m. to 11.30 a.m.) = 8 × $2.25 = $18
Now, the parking rate for the remaining 15 minutes (11.30 a. to 11.45) a.m. = $2.25
So, total amount he had to pay = $(6.50 + 18 + 2.25) = $26.75
