so
10+10+25+25+5+5+5=85

2. YIYI says:

1.35 because
25+25=50
50+10=60
60+10=70
70+5=75
75+5=80
80+5=85
85+25=110
110+25=135

.85+.25=1.10
.50+.65=1.15
.70+.80=1.50
.75+.50=1.25
.60+.45=1.05
.80+.50=1.30
.65+.45=1.10
.55+75=1.30

4. sloane says:

.85+.50=1.35
.85+.20=1.05

5. Yuvan says:

Its 85 cents and the other two mystery coins are 10 and 10, making the total to 1.05

6. Yuvan says:

o.85 + 0.10 + 0.10 = 1.05
0.85+ 0.10 + 0.25 = 1.20
0.85 +0.25 +0.25 = 1.35
0.85+0.25+0.05 = 1.15

4 different sums that makes greater than \$1.

the mystery coins might be
two .10 cents….85 cents +.10+.10=1.05
.25 and .5………85 cents +.25+.5=1.15
.25 and .10…….85 cents +.25+.10=1.20
two .25 cent….85 cents +.25+.25=1.35

Ruhan says you first add: 25cents + 25 cents = 50 cents, you then add 10 cents + 10 cents to 50 cents = 70 cents, then you add 5 cents + 5 cents + 5 cents to 70 cents = 85 cents total that we have. The piggy bank can have either a loonie (\$1= 100 cents), or it could have a toonie ( \$2= 200 cents). Then we add \$85 cents + 100 cents = \$1.85, and we can 85 cents + 200 cents = \$2.85 cents. This means the missing coins that are in the piggy’s belly are \$1 and \$2. If you had \$1 or \$2 or 85 cents, you will have MORE than \$1 total amount of money. Ruhan did need help arriving at this, but we broke down the math to show how many cents make up each value of the coin.

10+10=20 25+25=50 10+5+5=20 =60 60 +5=75 +two 25¢ = 125

10. Ashley says:

10+10+25+25+5+5+5=85+10+5=100
100 equals 1 dollar.
So the 2 mystery coins are 10 and 5.

11. Damien says:

If the coins not in the piggy bank is 85 cents the mystery coins are a quarter making 1.35
