Answer:
She will have 142 watermelons
Step-by-step explanation:
First let's put our ratio
10 : 71
Since our lemons are now 20 instead of 10 we will divide 20 by 10 to see how many time we multiplied it by.
which equals 2
To find our water melon we will multiply it by 2
which equals 142
She will have 142 watermelons
We want to use elimination to solve
y = 0 (1)
x + y = 40 (2)
Multiply (1) by -1 to eliminate y.
-y = 0 (3)
Add (2) and (3).
x + y + (-y) = 40 + 0
x = 40
Answer: Multiply by -1.
Answer:
9
Step-by-step explanation:
40 dollars due up front
10 dollars made per sale
5 dollars lost per creation
Realistically speaking she is only making a $5 profit per box she sells;
<em>$5 used up for material cost, $10 made from sales </em><em>-5+10= 5</em>
To pay the $40 dollar for the booth she would need to make 9 sales with her current profit
<em>40/5 = 9</em>
