Part A:
x is how many mattresses
y is how much money in total
Company A is (30*x)+13=y 133
Company B is (28*x)+15=y 127
Part B:
Company B because the answer is 127 whereas Company A would charge 133.
Part C:
You would save $12 if you use Company B instead of Company A to buy 7 mattresses.
If we know that Sophie already has $14 saved up and that she plans to save $5 each week, we can find out how many weeks until she can get her jacket.
<u>$14 already saved up</u>
14 + 5 = $19 → first week
19 + 5 = $24 → second week
24 + 5 = $29 → third week
29 + 5 = $34 → fourth week
34 + 5 = $39 → fifth week
39 + 5 = $44 → sixth week
44 + 5 = $49 → seventh week
49 + 5 = $54 → eighth week
54 + 5 = $59 → ninth week
59 + 5 = $64 → tenth week
Therefore, it will take Sophie 10 weeks to save up enough money for her new jacket.
It will take her about 67 minutes .. ( rounded )
