I don’t know how to do these
4x+16=6x
16=2x
8=x
And 11y+6x=180 (line)
11y+6(8)=180
11y+48=180
11y=132
Y=12
Answer:
$4800
Step-by-step explanation:
Let x be the C.P of the painting.
Profit=10% of x
Profit=
If S.P increase by 240 then
Profit=15% of x=
For first case
S.P=C.P+ Profit
S.P=x+10x/100
S.P=
For second case
New S.P
=
According to question







Hence, the C.P of the painting=$4800
C, will reach his goal first. $5.25 ×18 gives him $94.5 a week and $94.5 ×8 =756.
