Answer:
It will take 7.8 hours to print designs on 1300 shirts
Step-by-step explanation:
We will use the ratio method to solve this question
∵ A machine prints designs on T-shirts
∵ It prints 500 shirts in 3 hours
∵ x is the number of hours to print 1300 shirts
→ By using the ratio method
→ shirts : hours
→ 500 : 3
→ 1300 : x
→ By using cross multiplication
∵ 500 × x = 1300 × 3
∴ 500x = 3900
→ Divide both sides by 500
∴ x = 7.8
∴ It will take 7.8 hours to print designs on 1300 shirts
