Jessica had a total of $150 to spend for her art class supplies. She has already spent $87 on fancy paper and shading pencils. She wants to buy some art sets that are on sale for $10 each, including tax. Enter the MAXIMUM number of art sets Jessica can buy with the remaining money.

J.R. simplified the expression 0.3(5 + 2.5x - 3.2). His steps are shown.

Step 1: 0.3(5 + 2.5x - 3.2)

Step 2: 5.3 + 2.8x - 2.9

Step 3: 5.3 - 2.9 + 2.8x

Step 4: 2.4 + 2.8x

Which statement identifies and explains the first mistake J.R. made?

• His first mistake was in Step 2. He added 0.3 to each term instead of multiplying by 0.3.

• His first mistake was in Step 2. He should have only added 0.3 to 5 instead of adding 0.3 to all 3 terms.

• His first mistake was in Step 3. When reordering the terms, the 2.8x should be negative and the 2.9 should be positive.

• His first mistake was in Step 3. When reordering the terms, 2.9 should be the coefficient of x rather than 2.8.
