Answer:
7 quarters and 3 dimes
Step-by-step explanation:
x: quarter y: dime
25x + 10y = 205
x+y=10
y = 10-x
25x + 10*(10-x) = 205
25x+100 -10x = 205
15x = 105
x = 7
7 = 10-7 = 3
$41.83
7.25% as a decimal is 0.0725.
multiply 39.00 by 0.0725 to get the tax.
the tax is $2.83 and the product is $39.00. that added together is $41.83.
81.27 is the answer to 21% of 387 so a good estimate would be 82
If i am correct i think it is 3× = 78 +×-2 idk but i think it that hopefully u get it right :)
