Answer 1

Answer:

a) 4 months

b) $600

Step-by-step explanation:

1. x - number of months the total amount paid to be the same for both stores.

2. That same amount for store A: $300 + 75 \times x$

3. That same amount for store B: $200 + 100 \times x$

4. Since it's the same amount for both stores we can make an equation:

• $300+75\times x=200+100\times x$
• $300-200=100x-75x$
• $100=25x$
• $x=4$

5. To find that same amount, we can use either side of above equation:

• $300+75\times 4=600$
