1. $5.99/ 1 pound* 1.75 pound= $ 10.4825.

Rounded to the nearest cent, the answer is C. $10.48.

2. With a = 2.4 , b = 0.237 , and c = 9.49:

c- 2ab
= 9.49 - 2* (2.4)* (0.237)
= 9.49 - 1.1376
= 8.3524

The answer is A. 8.3524.

3. 10/ (1 2/3)
= 10/ (5/3)
= 10* 3/ 5
= 6

The answer is B. 6.

1. 5.99 per poound
total cost=cost per pound times pounds
cost per pound=5.99
pounds=1.75
total cost=5.99 times 1.75=10.48
cost is $10.48




2. if a is 2.4 b=0.237 and c=9.49 evaluate c-2ab

so subsitue and use PEMDAS
9.49-(2)(2.4)(0.237)
multiplication
2 times 2.4=4.8
9.49-(4.8)(0.237)
4.8 times 0.237=1.1376
then subtraction
9.49-1.1376=8.3524
answer is 8.3524






3.
10 divided by 1 and 2/3
convert 1 and 2/3 into improper fraction which is 1 and 2/3=3/3+2/3=5/3
10/(5/3)
invert and multiply
[tex] \frac{10}{ \frac{5}{3} } times \frac{ \frac{3}{5} }{ \frac{3}{5} } = \frac{ \frac{30}{5} }{ \frac{15}{15} } = \frac{ \frac{30}{5} }{1} =[/tex] 30/5= 6/1=6
answer is 6






1. $10.48
2. 8.3524
3. 6
