Step-by-step explanation:
Answer:
2000 = 24x + 20y (x represents hours and y represents money per sale)
she must make 88 sales
Step-by-step explanation:
2000 = 24(10) + 20y
2000 = 240 + 20y
-240 = -240
1760 = 20y
/20 = /20
88 = y
<span>In one month:
Jon worked = 3hours less than Chaya
Angelika worked = 4 hours + Chaya
Together they worked 196 hours
Let Jon = X
Chaya = Y
Angelika = Z
=> X = y – 3
=> y = y
=> Z = y + 4
let’s find the value of Y
=> y + (y - 3) + (y - 4) = 196
=> 3y + 1 = 196
=> 3y = 196-1
=> 3y / 3 = 195 / 3
=> y = 65
Jon = 65 – 3 = 62
Chaya = 65
Angelika = 65 + 4 = 69
65 + 62 + 69 = 196</span>
