a vending machine sells chips at $0.40 and candy at $0.50. Last month, the vending machine yielded $152.80 with a sale of 328 items. how many packages of chips were purchased last month

Answers

112 bags of chips

The solution to the system of equations gives 112 chips and 216 candy.
The equations to solve are

x + y = 328
.40x + .50 y = 152.80

(x = the number of chips and y = the number of candy)

x = 40 cents bags, y = 50 cent bags

x + y = 328...x = 328 - y
0.40x + 0.50y = 152.80

0.40(328 - y) + 0.50y = 152.80
131.20 - 0.40y + 0.50y = 152.80
-0.40y + 0.50y = 152.80 - 131.20
0.10y = 21.60
y = 21.60/0.10
y = 216 <=== total 50 cents bags sold

x + y = 328
x + 216 = 328
x = 328 - 216
x = 112 <=== total 40 cents bags sold

Ray is late for work, but would like to drink some coffee before he leaves. The coffee in the pot is too hot, so Ray puts 20 small ice cubes in a mug before pouring in the coffee. The ice cubes measure 1 cm per side. The mug is cylindrical, and has a height of 9 cm and a base of 7 cm. What is volume of the coffee that will fill the mug after the ice cubes have been added (round to the nearest whole number)?A) 113 cm3.
Eliminate
B) 326 cm3.
C) 346 cm3.
D) 424 cm3.

Answers

B) 326 cm3.
The volume of the mug is $\pi r^(2) *h$
r - radius,
h - height

The radius of the mug is 7/2 (half the base) = 3.5cm

volume of the mug = 3.5^2 * PI * 9 = 346 cm3

20 ice cubes = 20 cm3 that you need to substract from 346, that gives 326 cm3.

The volume of the mug is the area of its base · the mug's height, or $\pi r^(2)$ h. This is 3.5 cm · 3.5 cm. · 9 · $\pi$ , or 346.2 $cm^(3)$ . The volume of each ice cube is 1 cubic centimeter, so 20 of them will occupy 20 $cm^(3)$ . This leaves 326 $cm^(3)$ for the coffee.

1) In 2001, there were about 62.5 thousand golden retrievers registered in the United States. In 2002, the number was 56.1 thousand. If the number of golden retrievers continues to decrease at the same rate, how many golden retrievers are there in the year 2010?(A) 64 thousand
(B) 12,864
(C) 4.9 thousand
(D) 132.9 thousand

Answers

62500 - 56100 = 6400 - number of retrivers u lost per year.
Answer need to be lower then 62,5 and 56,1 thousand so no (A) and not (D)
Number is reduce by 6400 and starting amount was 62500, 2 zeros and end must stay there in answer so not (B)
Then it must be (C)

Or u can calculate 62500 - 9*6400 = 4900
