A beverage company surveyed 450 adults to determine the demand for summer drinks.
Ganezh [65]

Answer:

174 people preferred drinking water.

Step-by-step explanation:

Given that:

A total of 450 males and females were surveyed.

203 were males.

Number of females = 450 - 203 = 247 females

247 females were surveyed.

Now, we will find the number of females who prefer water.

Let,

x be that number.

Total number of females = Soda + Iced tea + Lemonade + Water

247 = 28 + 44 + 67 + x

247 = 139 + x

247-139 = x

x = 108

Number of people who prefer water = 108 + 66 = 174

Hence,

174 people preferred drinking water.

The choir sold boxes of candy and teddy bears near Valentine’s Day to raise money. They sold 57 items altogether. Bears sold for
nevsk [136]

Answer:

19 bears, 38 boxes of candy.

Step-by-step explanation:

We can use a system of equations (b = # of bears, c = # of candy boxes):

<em>b + c = 57, 8b + 6c = 380</em>.

We can use substitution by isolating b in the first eq.: <em>b = 57 - c</em>, then substitution b with 57 - c in the second eq.: <em>8(57 - c) + 6c = 380</em>.

Then, we solve: 456 - 8c + 6c = 380, 76 = 2c, c = 38 candy boxes.

Finally we plug in 38 for c in the first eq.: b + 38 = 57, b = 19 bears.
