A 5 pound box of detergent costs $0.175 per load ($3.50÷20).
One load of laundry takes 0.25 pounds of detergent (5÷20). This means a 15 pound box can wash 60 loads of laundry (15÷0.25).
A 15 pound box costs about $0.167 per load ($10÷60).
Using a 15 pound box, you will save $<span>0.008 per load ($0.175-$0.167).</span>
Answer:
f(2) = 7
Step-by-step explanation:
To figure this out you just have to plug in 2 wherever x is in the equation.
f(2) = 5(2) - 3
Multiply 5 by 2
f(2) = 10 - 3
Subtract
f(2) = 7

Answer:
Step-by-step explanation:
2.
Step where it was wrong ->
x-8 = 0
x=-8
They just put negative eight on the right side you have to cancel negative 8 out by adding negative 8 on both sides.
x-8=0
+8 +8
x=8 <- Right solution.
3.
Step where it was wrong ->
8(p-7) = 75
8p-7=75
Distributive Property you have to do 8 times p and 8 times -7, they just did 8 times p and forgot to do 8 times -7.
8(p-7)=75
8p-56=75 <- Do 8 * -7 in addition of doing 8 *p
8p=131
/8 /8
p = 16.735 or 131/8
