Answer: 1144
Step-by-step explanation:
Given: Machine A makes 7 parts every 10 minutes.
i.e. it makes parts in 1 minute.
Machine B makes 16 parts every 15 minutes.
i.e. it makes parts in 1 minute.
On Monday,
machine A makes parts for 12 hours(720 minutes). [1 hour = 60 minutes, 12 hours = 12 x 6 = 720 minutes]
i.e. Total parts made =
i.e. Total parts made = 504
machine B makes parts for 10 hours(=60x 10=600 minutes)
i.e. Total parts made =
i.e. Total parts made = 640
Total parts made by both machines = 504+640 =1144
Hence, the total number of parts made by the two machines on Monday=1144.
Pint:
16 oz size for $3.98 - $1.00 coupon
total value: $2.98
Quart:
We have 32 oz for $5.98, but to compare the value we need 16 oz so divide both side (quantity and price by 2)
16 oz for $2.99 - $0.50 coupon
total value (16) : $2.49
total value (32): 2.49 + 2.49 = $4.98
Answer: Quart is better to buy
