Question

equation 1: $0.40 + ? = $1.00
make an expression that shows one way to make $1.00 starting at $0.40.
$0.40
$0.40
$0.20 $0.40 +
$0.60 $0.80

Explanation:

Step1: Find the missing amount

We know that \( \$0.40 + x = \$1.00 \), so we solve for \( x \) by subtracting \( \$0.40 \) from \( \$1.00 \). That is \( x=\$1.00 - \$0.40=\$0.60 \).

Step2: Form the expression

Using the found value, the expression is \( \$0.40+\$0.60 \).

Answer:

\(\$0.40 + \$0.60\)
