Write and evaluate the expression. Then, select the correct answer. ten times the sum of seven and a number;
evaluate when j = 1

A 2-column table with 5 rows. Column 1 is labeled Key Words with entries ten, times, the sum of, seven, a number. Column 2 is labeled Replace with entries 10, times, (+), 7, j.

10 × 7 + j; when j = 1, the value is 71
7(10 + j); when j = 1, the value is 77
10(7 – j); when j = 1, the value is 60
10(7 + j); when j = 1, the value is 80
