Since the company spends 20$ on each doll and sells each for 30$ thats a 10$ profit.
If the company spends 400$ on promotion it would take 40 dolls since
400$ / 10$(amount of profit per doll) = 40
so to make the promotion back it would be 40 dolls but the question was to make PROFIT so it must be 41 dolls
Answer:
B is the answer. It keeps going up by 3 every time.
Step-by-step explanation:
Yes. It is a linear function. Slope-intercept form: y = x + 1.
Answer:
The exponential equation is 2^-5 = 1/32
Step-by-step explanation:
When rewriting the equation, we always take the base (2) and raise it to the answer (-5). Then we set that equal to the term (1/32)
2^-5 = 1/32
Marcia dissolved 1 kg of salt in 3 litres of water.
Bobby dissolves 2 pounds of salt in 7 pints of water
2.11 pints = 1 litre
7 pints = 7/2.11
= 3.32 litre
1 pound =0.45 kg
2 pound = o.45*2 kg
= 0.9 kg
So we find that Bobby is dissolving 0.9kg of salt in 3.32 litre of water
Marcia is dissolving 1 kg of salt in 3 litres of water.
