Answer:
3months
Step-by-step explanation:
target $1100
currently saved $1100
so we get the amount she need to save to get to the target.
$1100 - $110= $990 Need to be saved
saving rate 10% of $3300= $330 per month
to get the number of months she need to save, we divide amount needed by amount saved per month; $990 ÷ $330= 3months
y=32
cross multiply
36/4 *144/y
144*8/36
=1152/36
x=7
make the equations equal each other
72=6x+30
subtract 30
42=6x
divide by 6
42/6=7
