3 3/6 - 1 4/6 equals 1 5/6
Answer:
Peggy sold 41 brownies.
Step-by-step explanation:
She sold three more brownies. 1 brownie cost $3.00, so 3 brownies cost $9.00 because 3×$3.00.
$218-$9 = $209
Figure out the cost of 1 cookie and 1 brownie: $3.00+$2.50=$5.50
$209÷$5.50=38
This means that Peggy sold 38 cookies.
Since she sold 3 more brownies than cookies, add 3 to 38.
3+38=41
So, Peggy sold 41 brownies.
Take 79.2 ÷ 100 = 0.792 as a decimal
