Answer:
yes
Step-by-step explanation:
s + 2c = 47
5s+8c = 200
which one checks as in the other solution does not have a solution in non-negative integers. On the other hand, the analogous system
s + 2c = 47
5s+8c = 201
with solution s=13 and c=17. So, as in the other solution, we conclude that the extra dollar belongs in the cash box, with 13 singles and 17 couples attending the dance.
Answer:
a) The equation will you use to find the number of weeks x you will need to save is:
270 = 95.50 + 20x
b) The number of weeks x = 8.725 weeks
Step-by-step explanation:
Let:
The cost to join the Ski club = y
The number of weeks you will need to save = x
From the question, we have the following information:
The cost to join the Ski Club is $270. You pay a deposit of $95.50 and plan to save an additional $20 per week to pay for the cost.
The equation will you use to find the number of weeks x you will need to save is:
y = $95.50 + $20 × x
y = $270
Hence:
270 = 95.50 + 20x
Solving for x
270 = 95.50 + 20x
270 - 95.50 = 20x
174.5 = 20x
x = 174.5/20
x = 8.725 weeks
Hence, the number of weeks needed to save is 8.725 weeks
