TACO TIME

UNDERSTAND

• If a total of 4 tacos and 3 cokes costs $17
• and 2 tacos and a coke costs $7.80,
• how much would 1 coke and 1 taco cost?

PLAN

• Guess & check
• Work it out
• These methods helped us find the price of the taco and coke

SOLVE

• 4t+3c=$17
• 2t+1c=$7.80x2
• $17-$15.60
• 1coke=$1.40
• 1.40(3)=4.20

SOLVE

• 17-4.20=12.80
• 12.80\4=3.20
• 7.80-1.40=6.40/2=3.20
• 1 taco=$3.20

CHECK

• (3.20)4
• (1.40)3
• (3.20)2
• (1.40)1
• = $24.80
