Let
x = base pay per month
y = commission per $1 of sales
Then the monthly pay for selling $100 of merchandise is
P = x + 100y
In one month, Alyssa earned $388 for selling $400 worth of merchandise.
Therefore
x + 400y = 388 (1)
In another month, she earned $520 for selling $1000 worth of merchandise.
Therefore
x + 1000y = 520 (2)
Subtract (1) from (2).
x + 1000y - (x + 400y) = 520 - 388
600y = 132
y = 0.22
From (1), obtain
x = 388 - 400y = 388 - 400*0.22 = 300
When Alyssa sells $3300 worth of merchandise, she earns
300 +0.22*3300 = $1026
Answer: $1026
First option because the (or) means the arrows aren’t connected and the open circle means not equal to and closed circle vice versa
16 cm -10 days
1 cm --- x days
x=1*10/16=5/8=0.625 days
Ratio is 10:11
10+11=21 units
42 divided into21 is
42/21=2
each unit is 2
girles=10 units=10 times 2=20
boys=11 units=11 times 2=22
20 girle
