Let x = quantity of bicycles
($160x) - ($80x) = $2800. To solve for x, we have to combine the terms on the left side.
$80x = $2800. Divide each side by $80.
x = 35.
35 bicycles must he sold each month to break even.
Jane is given a $100 gift to start and saves $35 a month from her allowance.
After 1 month, Jane has saved
After 2 months, Jane has saved
After three months, Jane has saved
and so on
In general, after x months Jane has saved
This means that it makes sense to represent the relationship between the amount saved and the number of months with one constant rate (in this case the constant rate is 35). It makes sense because the amount of money increases by $35 each month. Since the amount of increase is constant, we get constant rate. Also the initial amount is known ($100), so there is a possibility to write the equation of linear function representing this situation.
Step-by-step explanation:
To turn a decimal into a percentage, multiply the decimal by 100 and add a percent sign.
.166 x 100=16.6
And add a percent sign
16.6%
Hope this helps.
