Call the number of pizzas x;They buy pizzas from the supplier at:4x+100They sell at:7xWhen these two expressions match they will start to make a profit; so:4x+100=7xRearranging:3x=100x=1003=33.3So after the 33rd pizza they will start to make a profit.For example at the 34th they have payed:34%C3%974+100=236$ to the supplier;Selling they will get: 7%C3%9734=238$. sorry if this is complex
Answer:
Y=MX+B
Step-by-step explanation:
put -1 on the y axis then go up 4 (3) after that go over 1 to the right since it's positive
So, 27=30 and 18=20 rounded
so what you would do now is multiply 30 x 20 and you get $600
Answer:
x=1
Step-by-step explanation:
First you would do the parentheses.
So, 4 x X= 4x
4x2=8
4x+8=2x+10
subtract 2x on both sides
2x+8=10
subtract 8 from both sides
2x=2
x=1
