CARD 01 • Diner Bill $75.00
Food bill: $60. Tip: \(0.20 \times 60 = \$12\). Tax: \(0.05 \times 60 = \$3\).
Total = \(\$60 + \$12 + \$3 = \mathbf{\$75.00}\).
CARD 02 • Unit Rates Deal A, by $0.25
Deal A: \(\$18 \div 12 = \$1.50\text{/bar}\). Deal B: \(\$14 \div 8 = \$1.75\text{/bar}\).
Deal A is cheaper by \(\$1.75 - \$1.50 = \mathbf{\$0.25\text{ per bar}}\).
CARD 03 • Submarine -190 meters
\(-420 + 185 - 75 + 120 = \mathbf{-190\text{ meters}}\)
(190 meters below sea level).
CARD 04 • Scaling Recipe 1 2/3 cups
\( \frac{2}{3} \times 2 \frac{1}{2} = \frac{2}{3} \times \frac{5}{2} = \frac{10}{6} = \mathbf{1 \frac{2}{3}\text{ cups}} \) brown sugar.
CARD 05 • Double Discount $81.00
25% off $120 = \(\$120 - \$30 = \$90\).
Extra 10% off $90 = \(\$90 - \$9 = \mathbf{\$81.00}\).
Common error: 35% off $120 = $78 (wrong!).
CARD 06 • Paint Ratio 21 quarts
\( \frac{\text{Blue}}{\text{Yellow}} = \frac{3}{5} = \frac{x}{35} \).
Multiplier is \(35 \div 5 = 7\). Blue = \(3 \times 7 = \mathbf{21\text{ quarts}}\).
CARD 07 • Exponents 89
\((-3)^4 = 81\) and \((-2)^3 = -8\).
\(81 - (-8) = 81 + 8 = \mathbf{89}\).
CARD 08 • Highway Distance 240 miles
3 hrs 45 min = \(3.75\text{ hours}\).
Distance = \(64\text{ mph} \times 3.75\text{ hrs} = \mathbf{240\text{ miles}}\).
CARD 09 • Garden Area 128 sq ft
Perimeter = \(2(16) + 2W = 48 \rightarrow 32 + 2W = 48 \rightarrow W = 8\text{ ft}\).
Area = \(16 \times 8 = \mathbf{128\text{ sq ft}}\).
CARD 10 • Percent Increase 25%
Increase = \(\$10 - \$8 = \$2\).
Percent change = \(\frac{2}{8} \times 100\% = \frac{1}{4} \times 100\% = \mathbf{25\%}\).
CARD 11 • Order of Operations -6
Inside: \(25 - 15 = 10\). Power: \(10^2 = 100\).
Division: \(100 \div (-5) = -20\). Addition: \(-20 + 14 = \mathbf{-6}\).
CARD 12 • Consecutive Integers 37, 38, 39
\(n + (n+1) + (n+2) = 114 \rightarrow 3n + 3 = 114 \rightarrow 3n = 111 \rightarrow n = 37\).
The numbers are \(\mathbf{37, 38, 39}\). Check: \(37+38+39 = 114\).
