d.51

Answer 1

In first  place you Know that Sheila's salary is  $ 1100 and $30 for every sale, as she want to earn  $2630  this month you must substrac 1100  of  2630

then $ 2630-1100 =  $1530 now you establish a proportion of quantities

1 sale_____ $30

x sale____ $1530    

X = 1*$1530/$30 =  51, SHE NEED TO MAKE 51 SALES TO OBTAIN $ 2630

Answer 2

first u multiply 30 by all those numbers

30 x 37= 1110

30 x 88= 2640

So in conclusion she needs to make 88 sales to reach her goal.
