Question #f7244
2 Answers
A:
B:
Explanation:
In order to do both, we should at least make an equation.
10x+5x+30=155.75.
(x is the amount of weeks, 30 is the money that we start with, and 155.75 is the amount of money that we are trying to reach.)
Let's combine like terms...
15x+30=155.75
Then isolate x by subtracting 30 on both sides...
15x=125.75
Divide both sides by 15....
For B, let's do the same thing
Isolate x by subtracting 30 on both sides....
A) 8.38 weeks
B) 3.21 weeks more
Explanation:
Money in hand = 30
Weekly saving = 5
Additional savings given by aunt every week = 10
Total savings per week = 15
A) No. of week required to meet the bicycle’s cost say x.
The equation is
B) if the cost of the bicycle is 203.89,
No. of weeks required to buy will be
Difference between (b) & (a) gives the no. of weeks more required to buy this bicycle.
