An estimate is a check, not a receipt

Let's make a plan someone can use. Six pretend kits cost $19 each, plus one $7 fee. A supplied budget is $120. What do we know? What are we trying to find? Make marks, move paper pieces, point, sign, talk or type. Give the quantities their own labels before you calculate. Here is one worked example: 6 × $19 + $7 = $121. The exact cost is $121, so it exceeds the $120 budget by $1. Rounding to 6 × $20 + $10 = $130 is a rough upper check, not the actual price. Now look back at the brief. Does our answer count the right thing and meet the supplied conditions? Four $18 kits plus a $7 fee cost $79. The upper rounded estimate $90 exceeds an $80 budget, yet the exact price fits. This counterexample prevents treating every upper estimate as a purchase decision. Take your time. Choose one of today's new briefs and make your own plan. A different correct strategy is welcome. Explain one check and one useful conclusion.
