So you do $90 times .40 because 40%=.40 then next you set up your problem
90x.40=36
In total the sales price is $36
If we have two numbers A&B and we know that A times B=0 then it must follow that either A=0, or B=0 (or both)
Answer:
The bag contains $5.14
Step-by-step explanation:
18% of 50 = (.18)(50) = 9 pennies
40% of 50 = (.40)(50) = 20 dimes
2 more nickels than pennies = 9 + 2 = 11 nickels
40 coins so far, so 50 - 40 = 10 quarters
Total value:
9 x ($0.01) = $0.09 for pennies
20 x ($0.10) = $2.00 for dimes
11 x ($0.05) = $0.55 for nickels
10 x ($0.25) = $2.50 for quarters
Grand total value = $5.14
I think the answer would be three because if you multiply all of the numbers together you get 30.
