Answer:

they sold 210 hot chocolates and 85 coffees

Step-by-step explanation:

We know that they sold $200 worth of drinks

x will be the number of hot chocolates sold

y will be the number of coffees sold

This means that

.75x+.5y=200

We also know that they sold 295 total drinks which means that

x+y=295

This is a system of linear equations which I will solve through substitution

x+y=295

Subtract y from both sides and divide by -1 to get

-x+295=y

Plug y into the first equation and get

.75x+.5(-x+295)=200

Distribute the .5 and simplify to get

.75x-.5x+147.5

.25x+147.5=200

Subtract 147.5 and then divide by .25 to get our x value

x=210

Now we can go back and plug this in into our equation

210+y=295

Subtract 210 to get y

y=85

This means that they sold 210 hot chocolates and 85 coffees

Answer:

-9 = 0.45m

Step-by-step explanation:

0.45m - 9 = 0.9m

  • ^ Subtract 0.45m from BOTH sides. so 0.9m - 0.45m... etc
  • Why? So that we can make the equation less complicated. Our goal is to isolate the variable m to be on one side of the "=" sign by itself
  • That will equal to:

-9 = 0.45m     <-- ANSWER

Camellia earned $160 over the summer. If you put 80% of earnings into her savings account and spent 75% of the rest on a gift fo
In-s [12.5K]

Answer: She has left over $8.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

<em>Camellia earned $160 and you put 80% of earnings into her savings account: </em>

So, to obtain this number we have to multiply Camellia's earnings by 0.80 (the percentage in decimal form, 80 /100 = 0.80)

$160 x 0.80 = $128 (savings)

If we subtract the number obtained to Camellia's earnings:

$160 -$128 = $32 (money left without purchasing a gift)

<em>She spent 75% of the rest on a gift for her </em>

The rest is $32, so we have to multiply it by the percentage in decimal form (75/100=0.75)

$32 x 0.75 (decimal form) = $24

And finally, subtract that number to the original rest.

$32-$24 = $8

She has left over $8.
